Question

which of these
will not give hydrolysis

​

Answer 1

Explanation:

Na

2

​

SO

4

​

 is a salt of strong acid and strong base. Salt of strong acid and strong base will not undergo hydrolysis.

Na

2

​

SO

4

​

→H

2

​

SO

4

​

→strong acid and NaOH→ strong base

∴Na

2

​

SO

4

​

 will not undergo hydrolysis.

Whereas FeSO

4

​

 is a salt of weak base Fe(OH)

2

​

 and strong acid H

2

​

SO

4

​

, K

2

​

CO

3

​

 is a salt of strong base KOH and weak acid H

2

​

CO

3

​

. And CH

3

​

COONH

4

​

 is a salt of weak acid CH

3

​

COOH and weak base NH

4

​

OH thus all these salt will undergo hydrolysis.
