Q. Calculate the amount of crystalline oxalic acid (equivalent weight = 63 g/eq.) required to prepare 250 mL of a N10 oxalic acid solution.

The equivalent weight of oxalic acid in C2H2O4⋅2H2O is 63. The molecular weight of oxalic acid (C2H204) is 90. But since Oxalic Acid exists with 2 molecules ...

Oxalic acid Molecular formula is H2C2O4, Therefore, the equivalent weight of the oxalic acid is 126/2 = 63.

Calculate the amount of crystalline oxalic acid (equivalent weight = 63 g/eq.) required to prepare 250 mL of a N10 oxalic acid solution.

The equivalent weight of the acid is molecular weight (126 g/mol) divided by n-factor (valency=2). Therefore, we should divide 126 by 2. Thus, the equivalent ...
