Emily Carpenter Investigating Rates of Chemical Reactions. Planning. Introduction I am going to investigate how increasing the concentration of a substance affects the rate of reaction. I will be studying how increasing the concentration of Sulphuric acid affects the rate of reaction when added to Magnesium. The equation for this is: Magnesium + Sulphuric Acid ? Magnesium Sulphate + Hydrogen Mg (s) + H2SO4 (aq) ? MgSO4 (aq) + H2 Background Knowledge There are many factors that affect the rate of a reaction; these include temperature, concentration, catalysts and surface area. In my preliminary investigation I used the reaction between Sodium Thiosulphate Solution and dilute Hydrochloric Acid to study the effect of temperature on rate. When I mixed the reactants the solution went cloudy and eventually I couldn't see a cross on a piece of paper under the reaction vessel. I timed how long this took, then increased the temperature by 10?c and carried out the same experiment....
