Which of the following pairs of salts undergo hydrolysis?
-
AlCI3 and NH4CI
- AICI3 and NaCI
- FeCI3 and KCI
- Na2SO4 and K2 SO4
The correct answer is: A
Explanation
Salt hydrolysis is a reaction in which one of the ions from a salt reacts with water, forming either an acidic or basic solution.Salts can be hydrolyzed in water, If the salts at least consist of one weak base or weak acid, they can be hydrolyzed. On the other hand, if the salts are from a strong base and acid, they cannot be hydrolyzed.
Al and \(NH_4\) are from weak base \(Al(OH)_3\) and \(NH_4OH\) respectively while Cl is from a strong acid HCl
