Question

Salt of strong acid and weak base have $pH$ value :

• A. Less than 7
• B. More than 7
• C. Only 7
• D. Only 14

Answer 1

Answer: (A)

Less than 7

Salt of strong acid and weak base have $pH$ value less than $7$. The solution is acidic. The hydrolysis of such salts involves hydrolysis of only cations (cationic hydrolysis) yielding free protons.
$B^{+}+H_{2}O\rightleftharpoons H^{+}+BOH$

Hence, option $A$ is correct.
