NH(4)CN is a salt of weak acid HCN(K(a)=...

`NH_(4)CN` is a salt of weak acid `HCN(K_(a)=6.2xx10^(-10))` and a weak base `NH_(4)OH(K_(b)=1.8xx10^(-5))`. 1 molar solution of `NH_(4)CN` will be :-

A

neutral

B

strongly acidic

C

strongly basic

D

weakly basic.

Text Solution

Verified by Experts

The correct Answer is:
D
Since `K_(b)gtK_(a)`, the solution will be slightly basic.
