Which among the following salt solutions will undergo the maximum extent (degree) of hydrolysis in a — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

$NH_4Cl$ is a salt of a strong acid ($HCl$) and a weak base ($NH_4OH$). Its degree of hydrolysis ($h$) is given by $h = \sqrt{K_h/C}$ (assuming $h \ll 1$). Since $h$ is inversely proportional to the square root of concentration ($C$), the most dilute solution will exhibit the maximum degree of hydrolysis.
