Consider the titration of oxalic acid with NaOH: H2C2O4 + 2 NaOH Na2C2O4 + 2 H2O (a) A solution of oxalic acid is made by dissolving 1.845 g of H2C2O4 . 2H2O in distilled water to obtain 100.00 mL of solution. What is the molar concentration of oxalic acid in this solution? (b) If 27.43 mL of a NaOH solution are used to titrate to the end point 25.00 mL of 0.09881 M H2C2O4, what is the molar concentration of the NaOH solution?
