Q 1149312213.     `500` mL of `0.2 M` aqueous solution of acetic acid is mixed with `500` mL of `0.2` M `HCl` at `250^oC`.

(i) Calculate the degree of dissociation of acetic acid in the resulting solution.

(ii) If `6` g of `NaOH` is added to the above solution, determine the final `pH`

(assuming there is no change in volume on mixing, `K_a` of acetic acid is

`1.75 × 10^-5` mol/L).
