Title: To investigate how hydrochloric acid changes the rate of reaction. Aim: I will investigate how changing the concentration of hydrochloric acid affects the rate of reaction between hydrochloric acid and magnesium. Hypothesis: I predict that as the concentration of hydrochloric acid increases the rate of reaction will also increase. Also if I was to double the amount of hydrochloric acid particles, the reaction will be twice as fast. Background information: The concentration of a solution tells us how many particles (moles) there are in 1dm-3. The factors that can affect the rates of reaction are: * changes in temperature, * changing the pressure, * changing a surface area of a solid reactant, * adding a catalyst, * Changing the concentration of a reactant. The concentration of hydrochloric acid means how many particles of hydrochloric acid are in a given area. This means if you increase the amount of hydrochloric acid there will be twice as...
