What would be the `pH` of an ammonia solution if that of an acetic acid solution of equal strength is `3.2`? Assume dissociation constants for `NH_(3)` and acetic acid are equal.

A

`3.2`

B

`6.4`

C

`9.6`

D

`10.8`

Text Solution

Verified by Experts

The correct Answer is:
D
`14=pK_(a)+pK_(b)`
`pK_(b)=14-3.2=10.8`
