Unformatted text preview: Ryan O’Hearn Chemical Principles I I Lab - 1011.206.43 Lab #5: Reaction between Sodium Oxalate and Potassium Permanganate: Oxidation- Titration Reaction 22:29:00 Pu rpose To learn about different types of reactions, more specifically oxidation-reduction reactions, and how to determine how much oxalate in an unknown sample using titration. An oxidation reaction is one where there is a loss of electrons or an increase in oxidation state, where reduction is where electrons are gained. These two reactions happen together in order to have a redox reaction, where the number of electrons lost by one substance is gained by the other. In this experiment we will be testing for the reduction of potassium permanganate because it causes someone else to become oxidized, which can tell us when the reaction of completed. Procedure See “Chemistry 206 Lab: Chemical Principles I I Laboratory,” Lab #5: “Reaction between Sodium Oxalate and Potassium Permanganate: An Oxidation-Reduction Titration.” The only exception to this procedure is that the molarity of KMnO 4 was 0.130 M , and not a mixture of distilled water and KMnO 4 ....
