Vedclass · Answer

(A) $CuSO_4$ is a salt formed from $Cu(OH)_2$ (a weak base) and $H_2SO_4$ (a strong acid). In an aqueous solution,$Cu^{2+}$ ions undergo hydrolysis: $Cu^{2+} + 2H_2O \rightleftharpoons Cu(OH)_2 + 2H^+$. The production of $H^+$ ions increases the concentration of hydronium ions in the solution,making it acidic. Therefore,the $pH$ of the solution is less than $7$.

Why is the $pH$ of an aqueous solution of copper sulphate less than $7$?
