Question

Assertion: A salt of strong acid with a strong base does not undergo hydrolysis.
Reason: Hydrolysis products of a strong acid and strong base would be completely dissociated.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

A salt of strong acid with a strong base does not undergo hydrolysis. In this case, neither the cations nor the anions undergoes hydrolysis. Therefor the solution remains neutral. For example: in the aqueous solution of $NaCl$, its ions $N{a}^{+}$ and $C{l}^{-}$ ions have no tendency to react with $H^{+}$ or $O{H}^{-}$ ions of water. This is because the possible products of such reaction are NaOH and HCl, which are they completely dissociated. As a result, there is no change in the concentration of $H^{+}$ and $O{H}^{-}$ ions and hence the solution continues to remain neutral.
