The stems and leaves of many plants contain oxalic acid (H2C2O4) or sodium oxalate. A standard analysis for determining the amount of oxalate ion (C2O4 -2) in a sample is to precipitate oxalate out with the calcium ion. The reaction often involves the following reactants. Complete the following information for this reaction. Sodium oxalate and calcium chloride
