Question

amounts of oxalic acid required to prepare 1 litre N/30 solution​

Answer 1

Answer:

Amount of oxalic acid required to prepare 250mL. of N10. solution (Molecular mass of oxalic acid is 126.

Answer 2

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 gTo 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.
