10ml of oxalic acid is titrated with 3M NaOH till end point. In each experiment colume of NaOH used as

Then find molarity of oxalic acid.

10ml of 0.05M of KMnO_4 is titrated with 10ml oxalic acid. Find its strength

3.65gm equimole mixture of NaOH and Na_(2)CO_(3) is titrated against 0.1M HCl using phenolphathalein as an indicator, V_(1)mL of acid was required to reach end point. In another experiment 3.65gm of same mixture is titrated against 0.2M HCl using methyl orange as an indicator, V_(2)mL of acid was required to reach end point. V_(1)+V_(2) is :

A certain volume of a monobasic weak acid was titrated against 0.1 M NaOH solution . The end point reached upon addition of 30 ml of alkali . The pH of the solution upon the addition of 20 ml of alkali was 6.3 . Find K_(a) for the weak acid .

100mL of 0.2M benzoic acid (pk_(a)=4.2) is titrated using 0.2 M NaOH pH after 50mL and 100mL of NaOH have been added are :

A solution of a weak acid was titrated was NaOH. The equivalence point was reached when 36.12 ml of 0.10 (N) NaOH have been added . Now 18.06 ml of 0.10 (N) HCl was addd to the titrated solution . The pH was found to be 4.92 .What is K_(a) of the acid ?
