A0.210 mol dm-3 solution of potassium hydroxide was added from a burette to 25.0cm3 of a 0.160 mol dm-3 solution of ethanoic acid in a conical flask. given that the value of the acid dissociation constant for ethanoic acid is 1.74x10-5 mol dm-3, calculate the ph at 25oc after 8cm3 of potassium hydroxide solution was added
