Equilibrium

Question

Wired Faculty App

Equimolar solutions of the following substances were prepared separately, which one of these will record the highest pH value?

BaCl₂

AlCl₃

LiCl

BeCl₂

Solution

A.

BaCl₂

BaCl₂ is a salt of strong acid HCl and strong base Ba(OH)₂. So, its aqueous solution is neutral with pH 7. All other salts give acidic solution due to cationic hydrolysis, so their pH is less than 7. Thus, pH value is highest for the solution of BaCl₂.
