Elisa Giordano 9/20/06 Lab #1 Studying the Rate of the Reaction of Potassium Permanganate and Oxalic Acid INTRODUCTION The purpose of this lab was to study the rate of the reaction between two chemicals, in this case potassium permanganate, KMnO 4 , and Oxalic Acid, H 2 C 2 O 4 . To better understand how rates of reaction occur, varying amounts of the individual chemicals were combined in test tubes. By examining the differences at which the reactions took place, the study of Kinetics was better understood. EXPERIMENTAL PROCEDURES See Lab Manual *Changed: Drops were used instead of mL; assuming 1 drop = 0.05 mL DATA TABLE - Concentration of H 2 C 2 O 4 solution, mol/L .755 mol/L . - Concentration of KMnO 4 solution, mol/L .136 mol/L . - Room temperature, °C 21°C .
