# Problem: Oxalic acid dihydrate, H2C2O4 * 2 H2O (molar mass = 126.07 g/mol) is often used as a primary standard for the standardization of an NaOH solution. If 0.147 g of oxalic acid dihydrate are neutralized by 23.64 mL of an NaOH solution, what is the molar concentration of the NaOH solution? Oxalic acid is a diprotic acid. (What is the balanced equation?)
