Chemistry Coursework Reaction of Magnesium and Hydrochloric Acid Initial Tests Before starting the planning the amounts of all the chemicals needed to be tested to see how much needed to be used. So a few Initial tests were done. In them I tested for a suitable amount of acid that should be used. 50cm3 would be best. There was a test for the best amount of Magnesium used and how much gas should be collected each time. It would be best to use 0.06g of Magnesium and to collect 50cm3 of Hydrogen gas. The table below is of our results from these Initial tests. Test Acid 0.5M Mg Gas Collected Time (cm3) (g) (cm3) (sec) 1 50 0.1 20 45 2 50 0.6 20 61 3 50 0.6 50 163 Planning Aim To investigate how temperature affects the rate of reaction between Magnesium and Hydrochloric Acid. Key factors * Rate of Temperature: -Affect on rate increases. * Concentration of Acid: -Higher concentration results to more acid particles, which means more collisions. Affect on rate increases. Lower concentration results to less acid particles,...
