Question

What is equivalent weight of crystalline oxalic acid?

Answer 1

The Formula of oxalic acid is H2C2O4. 2H2O.Therefore, the equivalent weight of the acid is molecular weight (126 g/mol) divided by n-factor (valency=2)Therefore,126/2 = 63.

Answer 2

The equivalent weight is 63

Explanation:

Oxalic acid is a weak organic acid with formula HOOC-COOH. It is a dibasic acid as it can give two hydrogen ions. The molecular formula of oxalic acid is $H_2C_2O_4. 2H_2O$. The molar mass of it is 126 g/mol.

Since, it is an acid of dibasic therefore the n-factor for oxalic acid will be 2.

Hence,

$\text{Equivalent weight of the acid}=\frac{\text { Molecular weight}}{2}$

$\Rightarrow \text { Equivalent weight of the acid }=\frac{126}{2}=63$
