a buffer solution contain 0.1 mole per litres of acetic acid and 0.001 moles perlitre of sodium acetate. what will be its pH?(k=1.8×10-5)

The pH of the solution is 2.74.

Explanation:

To calculate the pH of the acidic buffer, the equation for Henderson-Hasselbalch is used:

        .......(1)

The power of the acid dissociation constant is the negative logarithm of the acid dissociation constant. The equation for it is:

       ......(2)

The chemical equation for the reaction of acetic acid and NaOH follows:

Given values:

Putting values in equation 2:

We are given:

= 0.1 M

= 0.001 M

Plugging values in equation 1:

Hence, the pH of the solution is 2.74.

the answer is 1 i believe

i think tornado but not 100%
