An excellent project, very perceptive - BACKGROUND INFORMATION What affects the rate of reaction? 1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. 4) Presence of a catalyst. In the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride. The hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste; corrode active metals, …showed first 75 words of 3084 total…

The other main thing that could have helped us to get more accurate results is we cold have swirled the reaction throughout it to stop the diluting of the acid and the bubbles of H2 being given off. If I had time I could have done the reactions a few more times to get a better set of results. This would have helped my graphs to show better readings.
