The pH of 0.1 M solution of the following salts increases in the order : — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

NaCl; Neutral solution; pH = 7 4 NH Cl ; Cation undergoes hydrolysis; pH less than 7 NaCN; anion undergoes hydrolysis; pH greater than 7 HCl; strong acid Thus, pH in increasing order 4 HCl < NH Cl < NaCl < NaCN ->
