Question

In which of the following salts, cation does not undergo hydrolysis but anion undergoes hydrolysis?

• A. $BaC{O}_3$
• B. $CaC{l}_2$
• C. $K_{2}C{O}_3$
• D. $NaN{O}_3$

Answer 1

Answer: (C)

$K_{2}C{O}_3$

Cation from strong base does not undergo hydrolysis whereas anion of weak base undergoes hydrolyze. In $K_{2}C{O}_3,C{O}_3^{2-}$ ion undergoes hydrolysis to form alkaline solution.
