Question

ASSERTION:
Aqueous solution of $C{H_3}COON{H_4}$ is found to be neutral.
REASON:
This salt does not undergo hydrolysis.
A.Both the assertion and the reason are correct and the reason is the correct explanation for assertion.
B.Both the assertion and the reason are correct and reason is not the correct explanation for assertion.
C.Assertion is correct but Reason is incorrect.
D.Both Assertion and Reason are incorrect.

Answer 1

First we have to define the salt hydrolysis and the process behind it. It is a reaction which is shown by a salt made by the reaction of a strong acid and a weak base. Then we can observe that in the given question, the $C{H_3}COON{H_4}$ is therefore, a weak salt made by weak acid ( acetic acid ) and weak base ( ammonia ). So that makes the assertion right. Then we have to give the correct reason behind it and see whether the reason is right or not.

Complete step by step answer:
Salt hydrolysis happens for the salts formed from a strong acid and a weak base. They will make an acidic solution when added to an aqueous medium. The reason behind this occurrence is because when the salt dissociates in the medium. Then the conjugate acid of the weak base will donate a proton, or one hydrogen ion. This when reacted with the water will form hydronium ions.
Now in the given question, the Ammonium acetate is a salt of weak acid and weak base. Here the weak acid is acetic acid and the weak base is ammonia. Therefore, Ammonium acetate on the hydrolysis will produce ammonia and the acetic acid, among which both of which will have an approximately equal degree of dissociation.
Therefore, the solution of ammonium acetate in the process of hydrolysis will give an equal number of hydrogen ions and hydroxide ions.
Therefore, we can say that the aqueous solution is found to be neutral.

So, the correct answer is Option C .

Note:
In the case of salt hydrolysis, we can say that such salts formed will contain a hydroxyl group that is directly bound to the metal ion in place of a water ligand. Therefore, the positive charge on metal ions will create a force of attraction to water. Whereas a Lewis base with a non-binding electron pair on the oxygen atom, and alters the water molecule's electron density.
