Tanya Hughes Experiment to consider a factor that affects the rate of reaction between marble chips and hydrochloric acid. Factor investigated I have chosen to investigate the effect of concentration of acid on the speed of the reaction Calcium Carbonate + Hydrochloric Acid v Calcium Chloride + Carbon Dioxide + Water (Calcium carbonate reacts with the hydrochloric acid to give Calcium Chloride and Hydrogen. Fizzing due to Hydrogen gas is given off.) Preliminary work I carried out a preliminary experiment using a computer simulation programme to give me an idea about what range of concentrations to use in my real experiment. I used a volume of 20cm³ hydrochloric acid and a mass of 1.00 grams for the marble chips, varying the concentration of the hydrochloric acid each time. I then repeated the preliminary experiment, using the equipment myself, with a range of different concentrations and masses of marble chips, in order to ensure what range of concentrations and...
