NEET Chemistry Solubility Product Assertion Reason Question
Assertion (A): The solubility product (Ksp) of a salt of a weak acid increases at lower pH. | Reason (R): At lower pH, the concentration of the anion decreases due to protonation, which increases the solubility of the salt.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context mentions that the solubility of salts of weak acids increases at lower pH due to decreased anion concentration from protonation, supporting both the assertion and reason.
