When CH 3 COONa is added to an aqueous solution of CH 3 COOH

Question

When CH 3 COONa is added to an aqueous solution of CH 3 COOH (A) The pH of the solution decreases (B) The pH of the solution increases (C) The pH of the solution remains unaltered (D) An acid salt is produced

Tardigrade Admin · Accepted Answer

Dissociation of CH 3 COOH is suppressed by the addition of sodium acetate ( CH 3 COONa ) due to common ion ( CH 3 COO -) effect. The [H+] decreases raising the pH of the acid solution.

Q. When $C H_{3} COON a$ is added to an aqueous solution of $C H_{3} COO H$

The pH of the solution decreases

The pH of the solution increases

The pH of the solution remains unaltered

An acid salt is produced

Dissociation of $C H_{3} COO H$ is suppressed by the addition of sodium acetate $(C H_{3} COON a)$ due to common ion $(C H_{3} CO O^{-})$ effect. The $[H^{+}]$ decreases raising the $p H$ of the acid solution.
