Assertion :- A solution of `NH_(4)Cl` in water is acidic in nature.
Reacon : - Ammonium ions undergo hydroysis to from `NH_(4)OH` .

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
`NH_(4)Cl_((aq))toNH_(4(aq))^(+)+Cl_((aq))^(-)`
`NH_(4)^(+)` ions formed, undergo hydrolysis with water to from `NH_(4)OH and H^(+)` ions. `NH_(4)OH` is a weak base and thus remains almost unionised in solution. As a result, `[H^(+)]` ions increase in solution, making the solution acidic.

NH_(4)Cl is acidic due to

Aqueous solution of NH_(4)Cl is …… in nature due to behaviour of….ion in solution:

Assertion (A): On addition of NH_(4)CI to NH_(4)OH, pH decreases but remains grater than 7 . Reason (R) : Addition of overset(o+)NH_(4) ion decreases ionication of NH_(4)OH , thus [overset(Theta)OH] decreases and also pH decreases.

When NH_(4)Cl is added to a solution of NH_(4)OH :

When NH_(4)Cl is added to a solution of NH_(4)OH :

Assertion : The pH of NH_(4)Cl solution in water is less than 7 and pH of CH_(3)COONa solution is more than 7. Reason : NH_(4)Cl is a salt of weak NH_(4)OH and strong acid HCl whereas CH_(3)COONa is salt of a weak acid CH_(3)COOH and strong base NaOH.

Assertion: The pH of NH_(4)OH remains unchanged on addition of NH_(4)Cl . Reason : Addition of NH_(4)Cl suppresses the dissociation of NH_(4)OH due to common ion effect.
