The addition of sodium acetate to acetic acid solution will cause — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Sodium acetate introduces acetate ions ($\text{CH}_3\text{COO}^-$) into the solution. According to Le Chatelier's principle and the common ion effect, this suppresses the ionization of the weak acetic acid. This causes the concentration of hydrogen ions ($[\text{H}^+]$) to decrease, which consequently increases the pH.
