FAQs on Short Tricks: pH of Salt Hydrolysis Video Lecture - Chemistry Class 11 - NEET

1. What is salt hydrolysis?

Ans. Salt hydrolysis refers to the chemical reaction that occurs when a salt (formed by the combination of an acid and a base) reacts with water to produce an acidic or basic solution.

2. How does salt hydrolysis affect the pH?

Ans. Salt hydrolysis affects the pH by producing either an acidic or basic solution. If the salt is formed by the reaction of a strong acid and a weak base, the resulting solution will be acidic. Conversely, if the salt is formed by the reaction of a weak acid and a strong base, the solution will be basic.

3. What factors determine the pH of salt hydrolysis?

Ans. The pH of salt hydrolysis is determined by the strength of the acid and base used to form the salt. If the acid is strong and the base is weak, the resulting solution will be acidic. On the other hand, if the acid is weak and the base is strong, the solution will be basic.

4. Can you provide an example of salt hydrolysis affecting pH?

Ans. Sure! An example of salt hydrolysis affecting pH is when sodium acetate (NaCH3COO) is dissolved in water. Sodium acetate is formed by the reaction of acetic acid (a weak acid) and sodium hydroxide (a strong base). The hydrolysis of sodium acetate produces a basic solution with a pH greater than 7.

5. How can the pH of a salt hydrolysis solution be calculated?

Ans. The pH of a salt hydrolysis solution can be calculated using the concept of the ionization constant (Ka) and the concentration of the salt in the solution. The Ka value can be obtained from reference tables, and by using it along with the concentration, the pH of the solution can be determined using the appropriate mathematical equation.
