Ferrous Sulfate

Ferrous Sulfate, or iron(II) Sulfate, is a chemical substance composed of one iron electron and one sulfate Ion and has its chemical formula FeSO4. This green-blue crystal is widely utilized in many different applications like agriculture, medicine, and water treatment.

Ferrous Sulfate is a sought-after supplement used to treat and stop the development of iron deficiency anemia. In this condition, the body does not have sufficient iron to create enough hemoglobin. Ferrous sulfate also is utilized to treat restless leg syndrome. It’s also often used as a fertilizer for agriculture.

Properties Of Ferrous Sulfate

Ferrous Sulfate is an aqueous-soluble compound that can be readily absorbed into the bloodstream. It’s either light or white powder that has a slightly metallic flavor. Ferrous Sulfate is magnetic, which attracts magnetic fields and can be magnetized. The melting temperature of 680degC, and an optimum boiling temperature of 1,470degC.

Ferrous sulfate can be found in two varieties: the anhydrous type, devoid of water molecules, and the hydrated form, which contains some or all water molecules. The ferrous sulfate in hydrated form sulfur is commonly employed in agriculture and medicine.

Production Of Ferrous Sulfate

The reaction between sulfuric acid and iron normally makes Ferrous Sulfate. The iron used in the process is typically made of recycled iron or even iron files. The iron dissolves in sulfuric acid and results in the formation of ferrous sulfurate.

Another way to produce ferrous sulfate involves the oxidation of iron(II) Sulfate. This leads to the formation of iron(III) Sulfate. Finally, the iron(III) sulfurate is reduced to ferrous sulfur using sulfur dioxide or scrap iron.

Other Uses:

Ferrous sulfate can be used to make dyes, inks, and pigments. It also is used to make iron salts that are used for the treatment of wastewater and industrial.

Bond Angle

Bond Angle is among the most crucial chemical parameters that aid in creating molecules. It determines the shape of a molecule. It is the reason to ensure its durability and its reactivity.

A molecule’s specific geometry considers the various bond parameters, including length, distance, and angle. The parameters affect the correct geometrical arrangement of atoms and bonds within a molecule, affecting its reactivity, polarity, and phase of matter.

There are different types of molecule geometries such as linear, tetrahedral, trigonal planar, trigonal-bipyramidal, and octahedral – with their associated bond angles (Figure

 Linear Molecular

For linear molecules, carbon atoms in a linear molecule are placed so that their bonding moments are canceled. This is why CO2 is an ionic molecule.

Trigonal Plane

Molecules with trigonal plane forms are triangular or in a single plane, and the bond angle is set to 120deg. Examples include boron trifluoride as well as water (H2O).

An angular molecule has a nonlinear shape, and its bond angles typically are approximately 105 degrees. Therefore, they are SF4 as well as PCl5.


A tetrahedral molecular is slightly curled, and the bond angles typically are around 109.5deg however, it may not always exhibit this angle. This is because lone pairs might cause additional repulsions that make the optimal bond angles not right.

Optimal Bond Angles

The optimal bond angles are the angles that could be created if all electron domains around an atom were laid out in a perfectly symmetrical way. The VSEPR theory states that if all the electron domains were organized this way, the resultant arrangement would reduce the repulsion between an atom and nearby electron pairs.

However, since single pairs take up much more room than bonds, the molecular geometry is altered to give the lone pair more space. As a result, the bond angles tend to be less than optimal.

This is why tetrahedral and trigonal planar molecules don’t generally have optimal bond angles. Students must demonstrate why this scenario applies the VSEPR theory and the three points mentioned in the previous paragraphs.

To test their skills, students should sketch Lewis structures of a handful of molecules without ideal bond angles and identify why they don’t. This will allow them to understand that it’s not just the structure but rather the atomic repulsion which causes an error in the perfect geometry.

Molecular Geometry

Molecular geometry is the 3-dimensional arrangement of chemical bonds and atoms that comprise the molecule. It contains information about its shape, the form of the molecules, the length of bonds, bond angles, torsional angles, and various geometrical parameters that define the position of every atom within the molecule.

The shape of a molecule is determined by the number of electron pairs that valence around an atom’s central. The electron pairs repel each other due to a negatively charged electron cloud, and the locations where they are placed reduce the electronic attraction between them. This may alter the form of a molecule or ion by altering its bond angles and other physical characteristics.

Different Types Of Molecular Geometry

There are five different types of molecular geometry: linear, trigonal planar, tetrahedral, tri pyramidal, octahedral, and bipyramid. Each comprises atoms symmetrically organized around an atom central to it, which is the basis for the vertices.

For a molecule to be considered linear, it must possess an octet of electrons in the central atom and have no singular electron pair (bonding or not). The VSEPR code for a linear molecule is AX2AX2, in which “A” represents the central atom, and “n” represents the number of bonding electron pairs.

Molecules with an octet of electrons are called octahedral since the vertices on the molecule have eight faces, which is how the octal sign is utilized. Examples of octahedral molecules are sulfur hexafluoride, carbon dioxide, and sulfur.


The VSEPR theory suggests that molecules that contain an Octet of electrons that are lone pairs will exhibit an unbalanced or disorganized molecular shape. In essence, the repulsive interactions of the lone pair electrons and the electrons that bond to the central atom won’t be able to balance one another, resulting in the molecule becoming disorganized in its molecular structure.

Two primary geometries result from the theory of VSEPR, the linear planar and the trigonal. Trigonal planar molecules can be described as triangular, with bond angles of 120 degrees. The angular molecules are V-shaped. They have an angle of around 100deg.

Hybridization is the process that mixes non-atomic orbitals to create hybrid orbitals. It is possible to be observed with s and p orbitals.

Sp Hybridization

Sp hybridization can be described as the most well-known method of hybridization. It combines one and two orbitals with the same energy to create three identical orbitals, also known as the sp2 or hybrid orbs (Figure 3.). This kind of hybridization offers trigonometric geometry with an angle of bonding of 120 degrees.

This is what explains the trigonal planar structures of molecules such as C2H4. Each carbon contains two orbitals that mingle to two orbitals of 2p to create three SP2 orbitals. The sp2 orbitals are aligned with a trigonal planar shape that minimizes the repulsion of electrons and enhances the overlap.

The frontal and lateral lobes in these sp2 orbitals collide with the phases of their orbitals; they interfere destructively or constructively based on the shape of their phases. This is the reason why sp2 hybridization is an excellent illustration of polarity.

Sp3 Hybridization

Sp3 hybridization is an additional type of hybridization that occurs when an s and p orbital mixes. This results in creating a set of SP3 hybrid orbitals that coincide with the planar planes of the s and p orbitals.

In an sp3-hybridized molecule, the pi bond cannot be formed because there aren’t any non-hybridized p orbitals. This is because pi bonds can only occur in the presence of at least one unhybridized orbital left.

Understanding that this hybridization model can have distinct meanings for molecules with triple or double bonds is crucial. These are more complex than single bonds. Therefore the model must be able to account for them.

For instance, the molecule ethene (C2H4) is an ethene-carbon double covalent bond carbon atoms and one bond between every hydrogen atom. The hybrid bonds are described as, and it is explained through this hybridization theory.

Like the other nitrogen (N) molecules, they have a unidirectional bond between each hydrogen atom and an additional bond between carbon atoms. This is a double-bonded bond, and the hybridization theory explains it.

The PCl5 phosphorus pentachloride (PCl5) is a molecule with triangular bipyramidal geometry that includes an atom of the d sublevel. It may also function as a hybrid due to the effect of the electron-promoting of electrons from the 3s orbital to the open 3d orbital.

Polar Or NonPolar

The nonpolar and the polar molecules belong to two distinct types of molecules that are distinguished in how they distribute charge on their atoms or covalent bonds. In addition, polar molecules generally possess more electrically active properties than their nonpolar counterparts.

There are many methods to categorize molecules; however, the most popular method is to look at the Lewis structure. Lewis structure is an array of coordinates that indicate the positions of atoms within chemical compounds.

When the vectors of dipole moments have been arranged so that they don’t block each other out, the molecule will be, in fact, polar. Examples of polar molecules include water, hydrofluoric (HF), and alcohol methyl.

Another approach is to study the molecular anatomy of the molecule. This includes how the atoms are spaced apart in space. For instance, the lone pair of oxygen atoms on the central atom in water are pointed toward the outside. This is because the oxygen atom is more electronegative than hydrogen, which pulls on its electrons with greater force than the H atom.

The sum of dipole times in molecules can reveal whether it’s polar. The sum of these dipole times is referred to as net dipole moments, pointing outward, signaling the presence of a positive charge.

This is significant since a molecule’s polarity may influence chemical, physical and biological properties. For instance, the polar molecule is more than soluble in a polar solvent like water but less so in nonpolar solvents such as Hexane.


Polar molecules are generally Asymmetric, which means they have lone pairs of atoms of the central atom or atoms with different electronegativities that are bonded to them. The molecules that are not symmetrical can be polar because some or all of the atoms have an unbalanced pull on the electrons of other atoms and create dipoles.

The dipole moment in apolar molecules is opposite to that of nonpolar molecules since every dipole moment vector is directed toward the west, not toward an atom with greater electron density. This huge difference makes a polar molecule more appealing to electrons than a nonpolar one.

How To Determine Polarity And Nonpolarity Of FESO2 Compounds

When determining whether a compound is polar, it is important to consider the molecular structure. This could have a huge impact on the physical and chemical properties of the substance.

The VSEPR or valence shell electron pair (VSEPR) method is employed to study the geometrical structure of basic molecules. It outlines the five major molecular geometrics: linear, trigonal planar, tetrahedral bipyramidal trigonometric, and Octahedral.


What is FESO2?

FESO2 is a chemical compound also known as iron(II) sulfite or ferrous sulfite. It is composed of one iron (Fe) atom, one sulfur (S) atom, and two oxygen (O) atoms.

What is the bond angle of FESO2?

The bond angle of FESO2 depends on its molecular geometry. However, based on its Lewis structure, it can be assumed that the bond angles around the sulfur atom are approximately 120 degrees, which is typical for a trigonal planar arrangement of electron pairs.

What is the molecular geometry of FESO2?

The molecular geometry of FESO2 can be determined using VSEPR theory, which predicts the arrangement of electron pairs around the central atom. In this case, the sulfur atom has three electron pairs (two lone pairs and one bonding pair), which leads to a trigonal planar geometry.

What is the hybridization of FESO2?

The hybridization of FESO2 can be determined based on its molecular geometry. Since the sulfur atom has a trigonal planar geometry, it is sp2 hybridized, which means that its three atomic orbitals have been combined to form three hybrid orbitals with the same energy and shape.

Is FESO2 polar or nonpolar?

FESO2 is a polar molecule. This is because it has a trigonal planar molecular geometry, and the bond dipoles between the sulfur and oxygen atoms do not cancel each other out due to their unequal distribution around the central sulfur atom. As a result, FESO2 has a net dipole moment.

What are some of the properties and uses of FESO2?

FESO2 is a white solid that is insoluble in water. It is primarily used as a reducing agent in chemical reactions and as a preservative for food and beverages. It can also be used as a source of iron in the production of steel and other metal alloys.
