Calcium Hydroxide Reacts With Sulfuric Acid?

If calcium hydroxide reacts with sulfuric acid, there is a double displacement reaction which results in the formation of calcium sulfate and water. The chemical equation that is balanced to explain this process is:

Ca(OH)2 + H2SO4 – CaSO4 + 2H2O

In this equation, Calcium hydroxide (Ca(OH)2) and sulfuric acid (H2SO4) are the reactants, whereas calcium sulfurate (CaSO4) along with water (H2O) are the product.

In the reaction, the hydrogen ions (H+) from sulfuric acid react with the hydroxide-ions (OH+) of the calcium hydroxide to create water. Meanwhile, the calcium ions (Ca2+) from the calcium hydroxide mix with the sulfuric acid and ions (SO42-) from sulfuric acid to produce calcium sulfate. It is an insoluble substance that precipitates from the solution.

The reaction is exothermic, which means that it produces heat. However, it also generates lots of steam due to the formation of water, which appears as a white cloud in the air the mixture of reactions.

How To Balance:

Acid-Base Reaction

The Acid-Base Reaction involves the formation of salt (S) and water (H) from an acid and a base. This reaction is a common neutralization reaction and is important in everyday life. Calcium oxide, for example, is used to neutralize acidic soil, and hydrochloric acid in the stomach plays a vital role in digesting food. Antacids are bases commonly taken to neutralize excess stomach acid, which can cause gastrointestinal damage.

In Bronsted-Lowry terms, an acid can donate a proton (H+), while a base can accept a proton. Compounds that donate a proton are called monoprotic acids, while compounds that accept a proton are called polyprotic acids.

Strong acids dissociate completely in water to form the hydrogen ion H3O+(aq). Weak acids, on the other hand, dissolve only partially in the water. This is because the acid’s H+ ion is transferred to the water molecule, which acts as the base, rather than being abstracted by the water ion.

Many nonmetal hydrides, such as sodium hydroxy chloride, have hydrogen bound to them in the +1 oxidation state and thus can act as the source of an H+ ion in water. On the other hand, metal hydrides have hydrogen bound to them in the -1 oxidation state and, therefore, can only dissociate in water to form the H- ion.

Acid-base reactions are a basic chemical reaction involving protons (H+) transfer from acid to the base. These reactions are essential for various applications, ranging from biological systems to industrial processes. The article will look at the basics of acid-base reactions, such as their classification, examples, and applications.

What Are Acid-Base Reactions?

The acid-base reaction, commonly called a neutralization process, is when an acid reacts to a base to create salt and water. The acid gives proton (H+) to the base, which forms it as the base conjugate of acid and the acid that is the conjugate base from the base. The resultant solution is neutral and has a pH of 7.

Classification Of Acid-Base Reactions

The acid-base reaction can be divided into four distinct types according to the reactants and products involved. The four kinds of acid-base reactions include:

Reactions of strong acid and strong base: This reaction requires mixing a powerful acid and a base to produce salt and water. These reactions are typically exothermic and can be utilized to produce heat or electricity.


  • HCl(aq) + NaOH(aq) – NaCl(aq) + H2O(l)
  • HNO3(aq) + KOH(aq) – KNO3(aq) + H2O(l)
  • Reactions between weak acid and strong base: This reaction combines a weak acid with a strong base to produce water and salt. These reactions are not as exothermic as strong acid-strong base reactions and usually need an indicator to determine the point at which the reaction is over.


  • CH3COOH(aq) + NaOH(aq) – CH3COONa(aq) + H2O(l)
  • H2CO3(aq) + NaOH(aq) – NaHCO3(aq) + H2O(l)
  • The strong acid weak base reaction: This kind of reaction requires using a strong acid with a weak base to produce the salt and water. These reactions are not as Exothermic that strong acid and strong base reactions and typically require an indicator to identify the point at which the reaction is over.


  • HCl(aq) + NH3(aq) – NH4Cl(aq)
  • H2SO4(aq) + NH3(aq) – (NH4)2SO4(aq)
  • Reactions between weak acid and weak base: This reaction requires mixing a weak acid with weak bases to produce salt and water. They are generally slow and could necessitate the usage of catalysts to initiate the process.


  • NH4Cl(aq) + NaOH(aq) – NaCl(aq) + NH3(aq) + H2O(l)
  • HC2H3O2(aq) + NH3(aq)

What Is Neutralization Reaction?

A neutralization reaction is a kind of chemical reaction which occurs by the reaction of an acid with a base to create salt and water. This reaction neutralizes the reactants’ acidic and fundamental properties, resulting in a pH close to 7.0, which is considered neutral. The chemical equation used to describe the neutralization process is:

Acid + Base – water + salt

In this equation, the base and acid react to create the salt, composed of positively charged ions from the base and an ion negatively charged from the acid. The water molecule is created in the course of the process.

Common Reactions To Neutralization Include:

  • Antacid tablets help neutralize the acid in the stomach. The tablets are made up of bases like calcium carbonate that react with acid to create water and salt and reduce the acidity in the stomach.
  • Lime water is used to neutralize acidic soil. The lime reacts with the acid in the soil to create acid and water, making the soil less acidic and more alkaline.
  • Baking soda helps neutralize the acidity of spills. Baking soda is a base and reacts with the acid to create water and salt, which neutralizes the acidity of the spill.
  • The neutralizing properties of baking soda and vinegar are on the other. Vinegar is acid, in the same way that baking soda works as a base, which means that when mixed together, they mix to create the gas carbon dioxide, salt, and water.

Applications Of Neutralization Reactions

The neutralization reaction has a broad array of applications in a variety of fields, such as:

  • Treatment: Antacid tablets can reduce stomach acid and relieve heartburn and indigestion.
  • Agriculture: Lime is used to neutralize acidic soil that improves the development of crops.
  • Industries: The neutralization reaction treats acidic wastewater before it is discharged into the atmosphere.
  • Industries of the food industry: neutralization processes regulate the pH levels in food items that can impact the texture, taste, and stability.

Acid-Base Indicators

Acid-base indicators are substances that change color based on the acidity of the liquid they’re in. They can be used to determine the pH of a solution to determine if it is acidic or basic. Common acid-base indicators include:

  • Litmus paper: The paper is red when exposed to acid and blue when surrounded by the base.
  • Phenolphthalein: The colorless liquid transforms pink when in contact with an acid.
  • Methyl orange: This red liquid turns yellow when it is in contact with an acid.

With the help of acid-base indicators, scientists can identify the point at which they have reached a neutralization reaction: the point at which the acid has interacted with the base. It is at the point where the pH in the solution has been neutralized.

Exothermic Reaction

Exothermic reactions are a kind of chemical reaction that produces energies in the forms of light, heat, or sound. When an exothermic process occurs, the reactants lose energy when they create products. This means that the energy produced by the product is less than the energy of reactants, leading to the release of energy that is not needed.

Exothermic reactions can be spontaneous or not. Exothermic reactions that happen spontaneously happen naturally, releasing energy without any external influences, whereas non-spontaneous reactions require an external energy source to trigger the reaction.

Exothermic Reactions With Examples

There are numerous instances of exothermic reactions occurring in our everyday life. Here are some:

  • Reactions of combustion: Fuel combustion causes an exothermic reaction that releases light and heat. For instance, when we burn wood in a flame, the reaction creates heat and light. Light and heat.
  • The acid-base reaction: If an acid reacts with an element, the reaction creates energy by way of heat. This is why we feel warm when mixing vinegar and baking soda.
  • Reactions of neutralization: If the acid is reacted with the base makes salt and water. The reaction produces energy through heat. This is the reason you feel warm when you use an anti-acid tablet.
  • Reduction-oxidation reactions: The rusting process of iron can be described as an exothermic reaction that produces heat. This is an illustration of an oxidation-reduction process.

Importance Of Exothermic Reactions

Exothermic reactions are essential due to a variety of reasons:

  • Heating production: Exothermic reactions create heat in their byproducts that can be utilized in various ways. For instance, burning fuels like coal, oil, and gas release energy by way of heat that can be used to create energy, heat buildings, or power vehicles.
  • Industrial applications: A lot of chemical reactions that are used in industries are exothermic. For instance, manufacturing iron, cement, and steel are all exothermic reactions. These reactions are necessary to create the materials we need for manufacturing and construction.
  • Biochemical processes: A variety of biologic processes involve exothermic. For instance, the metabolism of food within our bodies produces energy by way of heat. The energy used drives different bodily functions, including muscle contractions or nerve impulses.
  • Safety factors: Exothermic reactions may also be hazardous if not properly managed. Fires and explosions could occur if the heat generated from an exothermic response has not been appropriately controlled. It is, therefore, crucial to be aware of the causes of exothermic reactions and how to control them to avoid accidents.

Arrhenius Equation

The Arrhenius equation is a mathematical formula that describes relationships between the speed of a chemical reaction and its temperature when it takes place. It was named for the Swedish scientist Svante Arrhenius who was the first to propose an equation as early as 1889. The equation is used in a wide variety that can be used in both chemistry and physical science, and it is used to study the effects of temperature on the reaction rate.

Which Equation Is Known As What Is The Arrhenius Equation?

The Arrhenius equation is an equation that connects the speed of a chemical process with the temperatures at which it takes place. This formula was developed on the concept that chemicals require certain amounts of energy to take place, referred to as activation energy. The equation is formulated by:

K is A * e^(-Ea/RT)

Where the rate constant is k, that is k, The pre-exponential coefficient and Ea is the energy of activation, and The gas constant is while T represents the temperature in Kelvin. The Arrhenius equation demonstrates the fact that the speed of the reaction grows exponentially with temperature. This means that even a slight temperature increase can have an impact on the speed of the reaction.

Application Of The Arrhenius Equation

The Arrhenius equation has numerous applications in physics and chemistry and can be used to determine the effects of temperature on the reaction rate. Here are a few examples of its usage:

  • Reaction Kinetics: The Arrhenius equation can be used to calculate the rate of chemical reactions at a specific temperature. By taking note of the reaction rate at different temperatures, the ability is there to determine the energy of activation and the pre-exponential factors of the chemical reaction.
  • Analyzing thermal effects: This is where the Arrhenius equation is employed in thermal analysis to calculate the energy that is activated by the reaction. This is done by monitoring the reaction rate at various temperatures and applying the results with an Arrhenius equation.
  • Chemical reactions within the air: The Arrhenius equation calculates the speed of atmospheric chemical reactions, like creating and degrading ozone. These reactions are crucial to understanding the effects of climate change and air quality.
  • Food preservation and processing: The equation of Arrhenius can be utilized to optimize the thermal processing of food to achieve its desired shelf life and sensory qualities while minimizing the loss of nutrients and energy use.
  • Reactions of polymerization: This Arrhenius equation is utilized to determine the best temperature for polymerization reactions and the shelf life of polymers.
  • In the case of corrosion: The corrosion: Arrhenius equation is used to determine the rate of corrosion in metals about temperature and to design materials resistant to corrosion.
