Vicki Biggs 11KB 17th February 2003 Rates of Reaction: Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid. Chemical reactions between substances are caused by the collision of particles. More collisions mean a quicker rate of reaction. In the reaction between hydrochloric acid and magnesium ribbon, the chemical reaction takes place when the magnesium ribbon is dropped into the hydrochloric acid. The products are hydrogen gas and magnesium chloride. The equation for this reaction is as follows:- Magnesium + Hydrochloric acid Magnesium chloride + Hydrogen Mg (s) + 2HCL (aq) MgCl2 (aq) + H2 (g) Factors that affect the rate of reaction:- * Temperature * Mass of magnesium ribbon * Concentration of hydrochloric acid * Surface area of magnesium ribbon I have chosen to use the concentration of hydrochloric acid as my independent variable. These different concentrations can be varied easily and made up accurately for the experiment. Each experiment will be done four times so that...
