Question

36. A salt of strong acid and weak base is dissolved in
water. Its hydrolysis in solution is
(1) Unaffected on heating
(2) Increased by adding strong acid
(3) Suppressed by diluting
(4) Suppressed by adding strong acid​

Answer 1

Answer:

A salt of strong acid and weak base is dissolved in water. It's hydrolysis in solution is supressed by adding strong acid.

the process of hydrolysis is actually the reverse of neutralisation

salt + water ⇌ Acid + Base.

now, as the acid is stronger and is also in the products side, addition of strong acid shifts the reaction to left side and thus, supressing the hydrolysis.
