Question

If 20ml of 0.4n naoh solution completely meutralizes 40ml of a dibasic acid . The molarity of the acid solition is

Answer 1

according to equivalent concept normality of NaOH X its volume =normality of dibasic acid x hits volume
so we can find me normality of the acid and because the acid is dibasic its molarity will be half times of its normality
so the molarity of the acid will be zero point 1
