The pH of an aqueous solution of ammonium acetate () is independent of its initial concentration. If — Ionic Equilibrium Chemistry Question
Question
The pH of an aqueous solution of ammonium acetate ($CH_3COONH_4$) is independent of its initial concentration. If diluted 100 times, its degree of hydrolysis ($h$) and pH will:
Answer: C
💡 Solution & Explanation
For WA-WB salts, $K_h = h^2 / (1-h)^2$, which is independent of concentration $C$. Thus, dilution does not change the degree of hydrolysis or the pH.
