Chemistry Pilot Experiment Aim The armorial bearing was to become accustomed to working with the equipment and to find optimum levels of hydrochloric tart and milligram ribbon to produce 60cm of hydrogen, a sensible amount to produce in the real experiment. We also began to investigate the effect of temperature on the rate and the conduce of the product (hydrogen). It also served to discover either errors in the turn which could touch the final result and prevent us getting accurate results, therefrom allowing us to eliminate these errors in the real experiment. Diagram Method We habituated a gas syringe via a plastic tube to a running play tube and used a clamp and stand to remove the gas syringe in place. Having poured 25cm of hydrochloric acid (of strength 1M) into the test tube, we situated a strip of magnesium ribbon (which space varied each time we repeated the procedure) in the test tube and rapidly pushed a rubber bung into th e top of the test tube to avoid any gas (hydrogen) produced in the fightion escaping. We then poured out the contents of the test tube and repeated the procedure apply the same amount of hydrochloric acid but a different length of magnesium ribbon. The next procedure we carried out involved changing another variable. Having discovered what length of magnesium ribbon would produce 60cm of hydrogen when allowed to react with 25cm of hydrochloric acid, we then used this length of magnesium ribbon and the same amount of hydrochloric but changed the temperature of the hydrochloric acid that was allowed to react with the magnesium ribbon to see if this had any effect on the chemical reaction by previously heating the hydrochloric acid to different temperatures using a Bunsen burner. We recorded the amount of hydrogen produced every 15 seconds using a stopwatch. Results This is a word equation for the reaction between magnesium and hydrochloric acid magnes ium+ hydrochloric acid magnesium chloride+ hydrogen Here is a table of the amounts of hydrogen produced when 25cm of
