Acid-Base Titrations And Acid-Base Neutralisation | nitric Acid And Potassium Hydroxide

If nitric acid (HNO3) and potassium hydroxide (KOH) are mixed in a reaction, they interact with each other, resulting in a neutralization process. Acid and the base form salt and water in this kind of reaction.

When it comes to nitric acids and potassium hydroxide, hydrogen ions (H+) from the Acid react with hydrogen ions of the hydroxide (OHand OH) in the base as per the chemical formula:

HNO3 + KOH – KNO3 + H2O

The equation is balanced and illustrates that one molecule of Nitric acid (HNO3) interacts with one potassium hydroxide molecule (KOH) to form one potassium nitrate molecule (KNO3) along with one water molecule (H2O).

The reaction is extremely exothermic, producing a substantial volume of heat. This is because the process requires the exchange of energy bases and acid molecules into the created water molecules. The heat released could be enough to cause the mixture to boil and then splatter, which could be hazardous.

It is, therefore, essential to handle nitric acids and potassium hydroxide with care and mix slowly with care to avoid overheating or spills. In addition, protective gear, like gloves, safety goggles, and a lab coat, must be used when working with these chemical substances.

When the reaction is completed, the product that results are potassium nitrate. It is a white crystalline salt often used in fertilizers, fireworks, and other uses.

How To Balance:

HNO 3 + KOH – KNO 3 + H 2O

Word formula: Nitric acid and Potassium hydroxide Potassium nitrate and water

Chemical Reaction Type: For the reaction, we are dealing with a chemical reaction of neutralization.

Balancing Strategies: This is a neutralization reaction with sodium hydroxide and nitric acids. Mix to create an acid (KNO2) as well as water.

Make sure you note both hydrogen atoms on the reactant’s side of the equation. For example, there is one hydrogen atom in the nitric acids and one in potassium hydroxide. This gives us two hydrogen atoms.

In balancing chemical equations, we aim to achieve the exact amount of each kind of atom in both equations.

Simply change these coefficients (these are the numbers that appear in the front of the substances).

Do not change the subscripts (the tiny numbers following elements).

Acid-Base Titrations

Acid-base titrations are a popular laboratory procedure used to establish the amount of an unidentified base or acid solution by mixing it with a solution of the same kind. In this procedure, the amount of the solution with an established concentration is gradually introduced into the unidentified solution until the reaction has completed. The point at which the reaction is completed is referred to as the”endpoint,” It can be determined using various methods, such as pH indicators or pH meters.

Acid-Base Titration Process

Titration of Acid-base requires a series of steps. First, the unknown solution is put in a flask. Then, a small amount of the indicator solution is put in. The indicator solution’s color changes when its pH alters and can help determine the conclusion of the process of Titration.

Then, a solution having an estimated concentration of the opposite kind (either one of the acids or the base) is gradually introduced into the flask by using an abrasive. It is then added drop-by-drop until the point at which the solution is finished. The endpoint is usually determined by watching a sudden change in the indicator’s color, which indicates that the base and Acid have fully reacted.

When the endpoint has been attained and reached, the volume of the already known solution added to the unidentified solution has been kept. With this volume and the concentration of the solution, it is possible to determine the amount of solution in the unidentified one. It could be determined by using the stoichiometry method of the reaction.

Types Of Acid-Base TitrationsPexels Mikhail Nilov 9243721 1

There are a variety of acid-base titrations, each having its distinct characteristics and functions. Some of the most commonly used types of acid-base titrations comprise:

  • Strong Acid Strong Base Titration: Titration occurs between a strong acid and a strong base. In this kind of reaction, your solution’s pH can change quickly near the point of equivalence, making it easier to identify where the reaction has ended.
  • Weak Acid Titration of Strong Base: This kind of Titration results from the reaction of weak acid and an extremely strong base. It is observed that the pH fluctuates gradually towards the equivalence point, which makes it harder to identify the point where the endpoint is. Color-changing indicators that can change across a broad pH range, such as phenolphthalein, are commonly used for this testing.
  • Strong Acid Weak Base Titration: This kind of Titration is a reaction of an acid with strong and weak bases. The solution’s pH fluctuates gradually near the equivalence level, making it difficult to determine the point at which the reaction is complete. Indicates that change color in various pH levels, like the methyl orange color, are commonly used in this type of testing.
  • Weak Acid weak base titration: This kind of Titration involves the interaction between two weak acids and a weak base. It is a process where the pH fluctuates slowly during titration, making it difficult to determine the point at which it will end. Indicates that change color in various pH levels, like bromocresol green, are commonly used in this testing.

Applications Of Acid-Base Titrations

Acid-base titrations can be used in a myriad of applications, such as:

Limitations Of Acid-Base Titrations

Although acid-base titrations are an effective method for measuring how much concentration is present in an unidentified substance, they have some limitations of this method. The most well-known problems include the following:

  • Interference: Impurities or other compounds in the solution under test could interfere with the precision of the determination of the Titration. This could result in inaccurate results and may require further tests to verify the concentration in the sample.
  • Human error: Human errors, like incorrect measurements or misreading the endpoints, can cause untrue results. The proper technique and attentive observation are necessary to reduce the chance that human error could cause.
  • Limitations of indicators: The selection of the indicator used during the titration process can affect the precision and accuracy of results. Some indicators do not offer the clearest color change at the point of termination or could alter color in too broad or a small interval of pH.
  • Limitation of The range of applications: Acid-base titrations can be limited to measuring the number of bases and acids which can be neutralized with the titrant utilized for Titration. This means that different types of solutions, like the mixture of bases and acids, cannot be precisely analyzed with this method.

Titration Of Weak Acid With A Strong Base

Titration is a method to determine the amount of an unidentified substance in a solution by mixing it with a well-known substance. In the article below, we’ll look at the titration procedure for a weak acid using an extremely strong base.

What Is A Weak Acid?

“weak acid” refers to one that does not fully dissociate in water. Instead, it breaks apart in small amounts, creating an unconjugated base and the hydronium ion. The most common weak acids are formic, acetic, carbonic, and formic acids.

What Is A Strong Base?

The term “strong base” completely dissociates from water and forms hydroxide Ions. The most common examples are sodium hydroxide, potassium hydroxide, and calcium hydroxide.

Titration Of Weak Acid Using Strong Base

Titration for a weak acid with an extremely strong base requires adding a predetermined amount of the solution for the strong base in the acidic solution until the equivalence level is attained. The Equivalence point is the place in the titration process where moles of Acid and those of the base solution are equivalent, and the solution turns neutral.

During Titration, the strong base interacts with the weak Acid neutralizing it and creating salt and water. The reaction can be modeled as follows:

HA + NaOH – NaA + H2O

HA is the weak Acid, and NaOH acts as the solid base. NaA is the sodium formed through the reaction.

At the beginning of the process, the solution is all the weak acids. When you add the solid base, the Acid’s pH rises as the Acid’s weak starts to separate. Its pH increases initially but gradually increases when the equivalence level is near. When the point of equivalence is reached, the pH of the solution is neutral.

Application Of Titration Of Acid That Is Weak Acid With A Strong Base

Weak acid titration using a strong base is widely used in analytical chemistry. It can determine the number of weak acids in solutions and its pKa, an indicator of its acidity. This technique is also employed in the manufacturing of pharmaceuticals. In addition, it can be used to test the quality of the drug.

Safety Precautions

When titrating, it is crucial to handle chemicals carefully. Both weak acids and strong bases can be harmful when not handled correctly. When working with these substances, it is vital to wear personal safety equipment, like gloves and goggles. You must work in a ventilated area to avoid exposure to vapors or fumes.

Percentage Purity Of Nitric Acid

Nitric Acid is an extremely toxic and corrosive liquid used extensively in various industrial processes. It is usually available in various concentrations that range from 50 to 70 percent. The Purity of nitric acids is the amount of nitric Acid present within the liquid. In the article below, we’ll examine how to determine the purity percentage of nitric Acid.

Calculating Percentage Purity Of Nitric Acid

The purity percentage of nitric Acid is determined by using the formula:

Percentage Purity = (Actual Concentration of Nitric Acid / Theoretical Concentration of Nitric Acid) x 100%

Its theoretical concentration for nitric Acid is the one that is predicted from how pure the Acid is used. For instance, if a manufacturer states that the nitric Acid they offer has 99% purity, the theoretical concentration of it is 99 percent.

The exact amount of nitric Acid in the solution can be measured experimentally by the technique of Titration. In this method, it is necessary to know the quantity of the nitric Acid solution titrated by an ordinary sodium hydroxide solution. The titration process stops once the equivalence level is reached and the amount of sodium hydroxide solution used is measured.

Based on this data, the exact concentration of nitric acids can be determined with the help of the following formula:

Actual Concentration of Nitric Acid = (Volume of Sodium Hydroxide Solution Used x Concentration of Sodium Hydroxide Solution) / Volume of Nitric Acid Solution Used

After the exact concentration of the nitric acids is determined, the percent purity can be determined using the formula above.

For example, suppose that we have a 50-ml sample of the nitric Acid solution, then titrate it using the 0.1 M solution of sodium hydroxide. It requires 20 milliliters of the sodium hydroxide solution to reach the equivalent point. We can determine the actual amount of nitric acids using the formula below:

Actual Concentration of Nitric Acid = (20 ml x 0.1 M) / 50 ml = 0.04 M

When the concentration that is theoretically for Acid nitric is 99% and the purity percentage of the nitric acids can be determined using the formula that was mentioned earlier:

Percentage Purity = (0.04 M / 0.99) x 100% = 4.04%

In this case, the Purity of the Nitric Acid is 4.04 percent
