500 ml of 0.2 M aqueous solution of acetic acid is mixed with 500ml of 0.2 M HCl at 25 degree celciusi) calculate the degree of dissociation of acetic acid in the resulting solution and pH of the solutionii)if 6gm NaOH is added to the above solution determine the final pH(there is no change in volume on mixing)Ka of acetic acid is 1.75*10^-5mol L-1
