The Effect of the Concentration of Hydrochloric Acid when reacting with Magnesium Key Variables * Volume of Hydrochloric acid * Concentration of hydrochloric acid * Temperature * Surface area I have chosen these variables because they all have an effect on the rate of reaction. The independent variable is the concentration of hydrochloric acid. It is the variable that I will be changing and observing. The other variables will be kept constant throughout. Prediction I predict that if I increase the concentration of the hydrochloric acid then the reaction between the hydrochloric acid and the magnesium will take place more quickly. This can be explained because of the following: The collision theory describes how the rate of reaction increases (the time taken for the magnesium ribbon to disappear when it is reacted with hydrochloric acid) when the concentration of HCL increases. The theory states that if, the more concentrated the reactants, the greater the number of...
