What is equivalent weight of oxalic acid

Method to calculate equivalent weight of oxalic acid

To calculate equivalent weight of oxalic acid you must have a clear concept on valency factor which we say n-factor , Equivalent weight of any molecule can be define as Molecular weight divided by n-factor ,

Equivalent weight. =  Molecular weight/n-factor

Now before answering to the question calculate equivalent weight of oxalic acid ? lets understand the rule to calculate Equivalent weight of acid

Acids : The number of moles of replaceable H+ ions per mole of the acid i.e.basicity.

For example, HNO₃; n = 1; H₂SO₄; n =2; H₃PO₄; n = 3, H₃PO₃; n = 2, H₃BO₃; n = 1

Oxalic acid Molecular formula is H₂C₂O₄

Oxalic acid Molecular weight is H₂C₂O₄.  =. 126

Oxalic acid n-factor =. Because it can give 2 H⁺ ion so n-factor= 2

We know that Equivalent weight. =  Molecular weight /n-factor

Therefore, the equivalent weight of the oxalic acid is 126/2 = 63.
