What will be the `pH` if `0.01 mol` of `HCI` is dissolved in the above buffer solution? Find the change in `pH` value.

How much moles of sodium propionate should be added to 1L of an aqueous solution containing 0.020 mol of propionic acid to obtain a buffer solution of pH 4.75 ? What will be the pH if 0.010 mol of HCI is dissolved in the above buffer solution. Compare the last pH value with the pH of 0.010 M HCI solution. Dissociation constant of propionic acid, K_(a) , at 25^(@)C is 1.34 xx 10^(-5) .
