An investigation to find out the rates of reaction between Magnesium and Hydrochloric acid

Introduction

        In my experiment I am going to investigate the rates of reaction. A 2cm strip of Magnesium is placed in a beaker full of Hydrochloric acid I will then time how long it takes for the magnesium to disappear. The concentration of the acid will be diluted and timed again. After collecting these results I will figure out the rate of reaction, and comment on the trends.

Equation

Magnesium + hydrochloric acid                             magnesium chloride + hydrogen

Mg    +    2HCl                        MgCl2    +    H2

Method

The experiment was set up as shown in the diagram. The experiment will be using 100cm3 Hydrochloric acid and will be changing the concentration every time by diluting the acid by substituting 10cm3 of acid for 10cm3 of water. We will do this process until we get 60cm3 of acid and 40cm3 of water, this will give me enough results to plot a table.

        To make this a fair test I will measure the Magnesium strip as accurately as I can. This will make my experiment a fair test also I will try to keep the beaker ...
