NEET Chemistry Solubility Product Assertion Reason Question
Assertion (A): The solubility of salts of weak acids increases at lower pH. | Reason (R): At lower pH, the concentration of the anion decreases due to its protonation.
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 explains that the solubility of salts of weak acids like phosphates increases at lower pH because the anion concentration decreases due to protonation, thereby increasing the salt's solubility.
