Chemistry Coursework I have been given the task for my coursework to investigate the effect of concentration on the rate of reaction. Equipment * 10g marble chips (calcium carbonate) * Measuring cylinder * Conical flask * Delivery tube * Goggles * Bowl * Stop watch * Hydrochloric acid * Water Method I will have 10g of marble chips in a conical flask and then put in 50ml of hydrochloric acid first and I will observe the reaction. With a stopwatch I will record every 20 seconds up to 3 minutes, I will measure the volume of gas given off by reading of the measuring cylinder. The second experiment I will do the same but this time I will have 45ml of acid and 5ml of water each time marble chips will remain 10g): Hydrochloric Acid (ml) Water (ml) 1st Experiment 50 0 2nd Experiment 45 5 3rd Experiment 40 10 3rd Experiment 35 15 4th Experiment 30 20 6th Experiment 25 25 The rates of the chemical reactions can be speeded up by: * Temperature -if temperature increases...
