Question

Which of the following salt gives anionic hydrolysis? (A)  NaCl  (B)  NaCN  (C)  NH4Cl  (D)  CuSO4

Tardigrade Admin · Accepted Answer

Salt of strong base and weak acid gives anionic hydrolysis. The anion of salt reacts with water to produce weak acid and OH- ion hence concentration of OH- increases and solution becomes basic. Example -NaCN CN-~+H2OHCN+OH~-

Q. Which of the following salt gives anionic hydrolysis?

$N a Cl$

$N a CN$

$N H_{4} Cl$

$C u S O_{4}$

Salt of strong base and weak acid gives anionic hydrolysis. The anion of salt reacts with water to produce weak acid and $O H^{-}$ ion hence concentration of $O H^{-}$ increases and solution becomes basic. Example $- N a CN$ $C N^{-} + H_{2} O H CN + O H^{-}$
