Magnesium Lab
Lab Report
Background Information:
Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong, silvery-white, light-weight metal (one third lighter than aluminum). In a powder, it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk, but once ignited, it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with a thickness of about 0.03mm, and weight of about 25 grams. Hydrochloric acid is a solution of hydrogen chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid.

Variables: Manipulated - Concentration of HCl
Responding - Reaction time of HCl and Mg
Controlled - Size of Mg piece, amount of HCl in test tube, room temperature, method of agitation.
Materials List: 1. Test tube rack 2. Graduated Cylinder (10mL) 3. 3 Test Tubes 4. 50 mL beaker 5. 250 mL flask (for the HCl) 6. Dropper 7. Stopwatch 8. 17cm strip of Magnesium Ribbon 9. HCl (.5 molarity) 10. HCl (1 molarity) 11. HCl (2 molarity) 12. Goggles 13. Scissors/Knife (for cutting Mg)
Procedure: 1. Cut the strip of magnesium into 10 mm pieces with the scissors/knife and then hold them in the beaker. 2. Measure out 5 mL of HCl (.5 molarity) with the dropper into the graduated cylinder. 3. Pour HCl (.5) from the graduated cylinder into the test tube. 4. Put a piece of magnesium into the test tube filled with HCl. 5. Start stopwatch when the magnesium is placed into the test tube filled with HCl (.5) and stop it when the magnesium has dissolved (flick the bottom of the test tube periodically to make sure that the magnesium mixes properly with the HCl). 6. Record your data and then dump out the HCl and wash your materials. 7. Repeat steps 2-6 with .5 molarity until you have completed 5 trials with it. 8. Get a new test tube. 9. Repeat steps 2-6 with 1 molarity. 10. Repeat steps 2-6 with 1 molarity until you completed 5 trials with it. 11. Get a new test tube. 12.
