Oxalic acid is a dibasic acid and available in crystalline form as (COOH)2 .2 H20. This is taken as primary standard for acids as it can be weighed accurately.

Equivalent weight of Oxalic acid = (Molecular weight / 2) = (126 / 2) = 63 g

• To prepare 1000 ml of 1 N Oxalic acid solution, the amount of oxalic acid required = 63 g.
• Therefore, to prepare 1000 ml of 0.1 N Oxalic acid solution, the amount of oxalic acid required = 6.3 g.
