A 1.876 g of the sample containing H2C2O4 requires 38.84 mL of 0.1032 M of NaOH for titration: H2C2O4 + 2 NaOH → Na2C2O4 + 2 H2O A 1.38 mL of 0.0992 M HCl is used in the back – titration. (a) Calculate the percentage of H2C2O4 in the sample. (b) Calculate the percentage expressed as the dihydrate, H2C2O4•2H2O.
