If 28.93 mL of a potassium permanganate solution was used to titrate 25.00 mL of a sodium oxalate soution made by dissolving 1.0423 g of sodium oxalate in 250.00 mL of water, calculate the molarity of potassium permanganate

1. Write the equation for the reaction taking place.

2. Work out the mole ratio of the reactants (How many moles of potassium permanganate react with how many moles of sodium oxalate.)

3. Find out the number of moles of oxalate ions used for the titration.

4. Use your answers to 2 and 3 to get the number of moles of potassium permanganate in the sample.

5. Use the volume and the number of moles of the potassium permanganate to get the concentration of the sample.
