The effect of concentration on the rate of reaction Aim: The purpose of this experiment is to find out if and how the concentration of a solution affects the speed of a chemical reaction. The reaction that I am going to study is magnesium and hydrochloric acid. Magnesium + Hydrochoric acid --> Magnesium chloride + hydrogen Mg(s) + 2HCL (aq) --> MgCl2 (aq) + H2 (g) Prediction: As we increase the concentration, the rate of reaction will also increases. The collision theory explains why the concentration affects the rate of a reaction. As the concentration of the acid increase, there are more acid particles in the same volume. Therefore, there is a great chance of acid particles colliding and reacting, with magnesium particles. So the rate of reaction will increase. Apparatus: * 20 cm of magnesium ribbon * scissors for cutting the magnesium ribbon * Emery paper to wipe off the deposit of magnesium oxide formed on the surface...
