Chemistry Pilot Experiment Aim The aim was to accommodate accustomed to working with the equipment and to find optimum levels of hydrochloric corrosive and atomic number 12 ornamentation to produce 60cm of hydrogen, a sensible amount to produce in the sincere experiment. We also began to investigate the effect of temperature on the rate and the result of the yield (hydrogen). It also served to discover any errors in the procedure which could affect the terminal result and prevent us getting accurate results, thus allowing us to eliminate these errors in the real experiment. Diagram Method We attached a catalyst syringe via a plastic pipework to a footrace tube and used a clamp and stand to hold the squander syringe in place. Having poured 25cm of hydrochloric acid (of strength 1M) into the test tube, we placed a strip of atomic number 12 thenar (which length varied each clock we repeated the procedure) in the test tube and rapidly pushed a good-for-naught bung into the top of the test tube to avoid any gas (hydrogen) produced in the reaction escaping. We then poured egress the contents of the test tube and repeated the procedure using the same amount of hydrochloric acid plainly 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 reaction by previously heating the hydrochloric acid to different temperatures using a etna 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 magnesium+ hydrochloric acid magnesium chloride+ hydrogen Here is a board of the amounts of hydrogen produced when 25cm of
