10/29/08 Magnesium and Hydrochloric Acid Lab What the Experiment Was: In this experiment, we were supposed to mix hydrochloric acid with solid magnesium. This was to be done in the lab, with a group of three. Here is the official problem: Starting with solid magnesium and 1 molar Hydrochloric Acid, conduct a metallic single replacement reaction to make 20mL of .5 molar magnesium chloride. Now for the process… Process: 1. The first thing we did was write out the equation, and figure out how much of each reactant we would need to complete the reaction as stated 2. This is the reaction we found, and balanced Mg(s) + 2HCl(aq) --> MgCl 2 (aq) + H 2 (g) 3. We were able to determine that the equation was REDOX, and that the Magnesium would be reduced. To balance this, the Hydrogen would be oxidized two times, hence the H 2 . 4. With this balanced equation, we were able to determine that 20mL of .5 molar Magnesium Chloride would be .01 moles. (molar = moles/liters) We used the molar relationship to determine that in order to conduct the reaction, we would
