Investigation- How does temperature affect the rate of reaction between Magnesium and Hydrochloric acid Planning Reaction = Magnesium + Hydrochloric acid = Magnesium Chloride + Hydrogen Balanced equation = Mg + 2HCl = MgCl2 + H2 Preliminary work: We are testing for problems before we begin the experiment so that we know what the problems are and how to overcome them, so our experiment will run more smoothly. Problem 1: The magnesium we are using has a magnesium oxide coating, so the acid has to react with the oxide first, slowing down the reaction. Solution: We will dip the magnesium in acid first, to remove the coating. We will then wash and dry the strip of magnesium before using it in the reaction. Problem 2: We want to control the temperature in the experiment, but as it is an exothermic reaction, heat is given off, which may change the rate of reaction. Solution:...
