A) \[NaCl\]
B) \[NaCN\]
C) \[N{{H}_{4}}Cl\]
D) \[CuS{{O}_{4}}\]
Correct Answer: B
Solution :
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\[-NaCN\] \[C{{N}^{-}}~+{{H}_{2}}OHCN+OH{{~}^{-}}\]
