Question
Station 2: Magnesium and Hydrochloric Acid
1. Carry your small graduated cylinder and ONE of your large test tubes in a 250 mL beaker to station
2.
2. Roll three magnesium strips into balls and drop them into the empty test tube.
3. Measure about 2 mL of 3 M hydrochloric acid in your small graduated cylinder.
4. BEFORE you add the 3 M hydrochloric acid to the magnesium, have your lab partner light a wooden
splint.
5. When ready with the splint, add the acid to the test tube with the magnesium ribbon, and immediately
have your partner hold the lit end of the splint inside the top of the test tube. NOTE: The flame should
not be placed so far down that it reaches the liquid in the test tube!
6. Record your detailed observations in the data section and return to your lab bench.
7. Add a pea size amount of solid sodium bicarbonate to the test tube, and then pour the entire contents
into your waste beaker. You can use water to dislodge any solids, but be sure to add this to the waste
beaker also.
