If `pK_(a)` of acetic acid and `pK_(b)` of ammonium hydroxide are `4.76` each. Find the pH of ammonium acetate.

A

7

B

Less than 7

C

More than 7

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
A

pH of a salt of weak acid and weak base is
pH = ` 7 + 1/2 pK_(a) - 1/2 pK_(b)`
`pH = 7+1/2 xx 4.76 - 1/2 xx 4.76 = 7`
