Oxalic acid, H2C2O4*H2O (molar mass= 126.07 g/mol) is often utilized as a primary standard for the standardization of a NaOH solution. If 0.117 g of oxalic acid dihydrate is neutralized by 19.55 mL of a NaOH solution, explain what is the molar concentration of the NaOH solution? Oxalic acid is a diprotic acid. Explain what is the balanced equation?
