Question

the aqueous solution of which of the following salt will have OH ions ?? (a) NaCl (b) Na2SO4 (c) CH3COONa (d) none of these​

Answer 1

Answer:

Ch3COONa is a basic salt and hence on hydrolysis will always give OH ions and thus in aqueous solution only basic salts gives basic solutions.

On the other hand NaCl is a neutral salt hence will always give a basic solutions.

Na2So4 is also a neutral salt as it is formed by combination of strong acid and base hence it will always be a neutral salt hence on in aqueous solution will give neutral solution.
