Question

If 0.231 g of oxalic acid dihydrate is neutralized by 31.75 mL of NaOH, calculate the molarity of the NaOH

Another solid acid that can be used as a primary standard is oxalic acid, which usually exists in the dihydrate form: H2C2O4·2H2O. 2NaOH (aq) + H2C2O4·2H2O (aq) -> Na2C2O4 (aq)+4H2O (l)
