Acetic acid is a weak monoprotic acid.

In aqueous solution, it has a pKa value of 4.76. Its conjugate base is acetate (CH3COO−).

A 1.0 M solution has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.

For acetic acid pKa =4.76 and –log(10)[H+] = pH

4.76 = log(10)(0.1) + 2*pH

=>2*pH=4.76 + 1

=> pH = 5.76/2

=> pH = 2.88

The required pH of 0.1 M solution of acetic acid is 2.88.

HLO FRND HERE IS UR ANSWER..

Acetic acid (CH3COOH) is a weak acid.

In aqueous solution,it has a pKa value of 4.76.

It's conjugate base is acetate (CH3COO-).

A 1.0M solution has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.

For acetic acid pKa = 4.76 and -log (10)[H+] = pH

→4.76=log(10)(0.1)+2*pH

→2*pH=4.76+1

→pH=5.76/2

→pH=2.88

The required pH value of 0.1 M solution of acetic acid (CH3COOH) is 2.88.

HOPE IT'S HELP YOU.
