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).
