Solution
Molar mass of oxalic acid dihydrate = 126g/mol
The molecule releases 2 H+ ions in solution on dissociation
Equivalent weight = Molar mass / replacable H+ = 126/2 = 63 g/mol
The molecule releases 2 H+ ions in solution on dissociation
Equivalent weight = Molar mass / replacable H+ = 126/2 = 63 g/mol
