Oxalic acid, H2C2O4, can be neutralized with a solution of sodium hydroxide, NaOH. a. Write a balanced chemical equation for this neutralization reaction. b. 15.00 mL of an oxalic acid solution of unknown concentration was titrated to an endpoint with 0.0988 M NaOH solution. If it required 31.65 mL of the NaOH solution to neutralize the H2C2O4, what was the concentration of the oxalic acid solution?
