Chemistry Investigation Speeding Up Reactions Ehtasham Junaid 11GD1 Fitzalan high school Tutor: Mr Dennis Chemistry Investigation - How do we make Magnesium and Hydrochloric acid react faster? Planning: Aim: This experiment is to find out how to increase the rate of reaction with magnesium (Mg) and hydrochloric acid (HCL) The word equation for the reaction is: Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen Symbol equation: Mg(s) + 2HCL(aq) MgCl2 (aq) + H2(g) There are four possible ways to change the rate of the reaction: * Change the temperature of the Hydrochloric acid * Change the surface area * Add a catalyst. * Change the concentration of the Hydrochloric acid Changing the temperature: If I undertake the experiment and change the temperature throughout, I will come across problems: It will be difficult to keep the temperature constant for the entire experiment. It will be very difficult to decrease the temperature below that of 'room temperature'. Hydrochloric acid can get dangerous at a high temperature. Changing the surface area...
