To investigate the effect of concentration on the rate of a reaction Magnesium + Hydrochloric Acid ---> Magnesium Chloride + Hydrogen Mg(s) + 2HCl(l) ---> MgCl2(l) + H2(g) Aim The aim of this investigation is to find out how the concentration of Hydrochloric Acid effects the rate of the reaction. In this case we will measure the rate at which Hydrogen is produced. The concentration of the Hydrochloric Acid will be our variable. Prediction I believe that the higher the concentration, the faster the rate of reaction. From preliminary experiments I have discovered that the higher the concentration of the acid, the more collisions there are. Therefore, the rate of reaction will be larger if we use a high concentration of the acid rather than using a smaller concentration. Procedure Experiment Acid Volume (cm3) Water Volume (cm3) Total Volume (cm3) Concentration (mol/dm3) 1 50 0 50 1m 2 40 10 50 0.8m 3 30 20 50 0.6m 4 20 30 50 0.4m 5 10 40 50 0.2m For the experiment we have chosen specific equipment. The equipment we have chosen was used in our preliminary experiment as was the magnesium. We...
