... Chemistry Coursework: PLAN Investigate the rate of reaction between different concentrations of hydrochloric acid with metal carbonates using calcium carbonate as the example. Apparatus For this experiment I will require the following apparatus; The apparatus will be set up as shown in the diagram above. I will begin timing each experiment when the necessary hydrochloric acid, water and calcium carbonate quantities are in the conical flask - and the top is sealed. Timing will stop once 50cm3 of gas has appeared in the measuring cylinder. Concentrations The concentrations I will be using during my experiment are as follows; Calcium Carbonate Granules (g) Hydrochloric Acid (cm3) Water (cm3) Concentration (%) 5.00 50 0 100 5.00 40 10 80 5.00 30 20 60 5.00 20 30 40 5.00 10 40 20 Using these concentrations will mean that a good range of results will be obtained, therefore making this experiment more reliable and easier to draw conclusions from. The calcium carbonate that is used will be in granules because:> They have a smaller surface area than powder, making the timing much easier.> They are
