Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to
