FAQs on Video: PH of Salts(in Detail) Video Lecture - Class 10

1. What is the pH of salts?

Ans. The pH of salts depends on the nature of the salt. Salts can be categorized as acidic, basic, or neutral based on their pH value. Acidic salts have a pH value less than 7, basic salts have a pH value greater than 7, and neutral salts have a pH value equal to 7.

2. How is the pH of salts determined?

Ans. The pH of salts can be determined by using a pH indicator or a pH meter. A pH indicator is a substance that changes color depending on the acidity or alkalinity of a solution. By adding a few drops of a pH indicator to a salt solution and observing the color change, we can determine the pH of the salt.

3. Give an example of an acidic salt and explain its pH value.

Ans. An example of an acidic salt is ammonium chloride (NH4Cl). When ammonium chloride dissolves in water, it undergoes hydrolysis and releases hydrogen ions (H+). These hydrogen ions make the solution acidic, resulting in a pH value less than 7.

4. Provide an example of a basic salt and explain its pH value.

Ans. An example of a basic salt is sodium carbonate (Na2CO3). When sodium carbonate dissolves in water, it dissociates into sodium ions (Na+) and carbonate ions (CO3^2-). The carbonate ions react with water molecules, producing hydroxide ions (OH-). These hydroxide ions make the solution basic, resulting in a pH value greater than 7.

5. Can salts be neutral? Provide an example.

Ans. Yes, salts can be neutral. An example of a neutral salt is sodium chloride (NaCl). When sodium chloride dissolves in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-). Neither of these ions reacts with water to produce hydrogen ions (H+) or hydroxide ions (OH-), resulting in a pH value equal to 7, which is neutral.
