Aim: The aim was to become accustomed to working with the equipment and to find optimum levels of hydrochloric acid and magnesium 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 result of the product (hydrogen). It also served to discover any errors in the procedure which could affect the final result and prevent us getting accurate results, thus allowing us to eliminate these errors in the real experiment. Diagram: Method: We attached a gas syringe via a plastic tube to a test tube and used a clamp and stand to hold the gas syringe in place. Having poured 25cm of hydrochloric acid (of strength 1M) into the test tube, we placed a strip of magnesium ribbon (which length varied each time we repeated the procedure) in the test tube and rapidly pushed a...
