Question
Molecular weight of dibasic acid is W. Its equivalent weight will be :
Solution
The molecular weight of a dibasic acid is given as W.
A dibasic acid is an acid that has two replaceable hydrogen atoms. Therefore, it can furnish two hydrogen ions (H+) per molecule in a solution.
The equivalent weight of an acid is defined as the weight of the acid that can furnish one mole of H+ ions.
Since a dibasic acid can furnish two moles of H+ ions, its equivalent weight will be half of its molecular weight.
So, the equivalent weight of the dibasic acid will be W/2.
