The Plan The problem To find out how the concentration of acid in rain affects the rate that limestone dissolves. I will measure the amount of gas that is produced by the different concentrations of acid. The more gas that is produced the more the limestone is being dissolved. Background knowledge Calcium carbonate + Hydrochloric acid Calcium chloride + Water + Carbon dioxide 1. Collision theory Concentration 2. Surface area 3. Temperature Prediction I think that as you increase the concentration of the acid more gas will be produced in the set amount of time. I think that if you double the concentration you will double the amount of gas produced: and the rate of reaction will also double. Apparatus * Water bath * Beehive * Measuring cylinder * Tubing * Bung * Conical flask * Limestone * Hydrochloric acid * Stop clock * Thermometer Method After setting up the apparatus you make a table for the results. You then add the limestone to the acid (making sure the bung...
