Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2.

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as
