##### balanced equation/ titration
« on: July 08, 2004, 11:14:11 AM »
If the question is : A 50.0 mL solution of H2C2O4 requires 24.35 mL of .125M NaOH to neutralize both protons. It takes 15.83mL of KMnO4 (product Mn2+) to react with all the oxalic acid in another 5.0 mL sample of oxalic acid (product CO2). A 2.500g sample containing iron(II)chloride is dissolved in acid and titrated with 31.87 mL of the KMnO4 solution.  How do you writie out the balanced equation for this reaction??? THere are three of them aren't there? And  how do you find the concentration of permanganate solution?

(1) H2C2O4 + 2NaOH => Na2C2O4 + H2O
