Magnesium Lab

You will need the following items: tripod stand, clay triangle, crucible with lid, electroni scale, Bunsen burner (with access to a source of gas), a striker or a lighter, and a few strips of magnesium. First, find the mass of the empty crucible, record. Then find the mass of the magnesium strips. Then, put the magnesium to the crucible and mass it together. hook up the Bunsen burner to the gas source. Place the tripod stand over the burner and place the clay triangle on the tripod stand. Turn on the gas and light the burner with the striker or lighter. Place lid on the crucible and carefully place the crucible, with the magnesium and lid, onto the clay triangle. Leave the lid on for a few minutes. Remove the lid. The magnesium should light on it's own but if it does not, take a pair of tongs, take out a piece and put in the fire. When it ignites don't look at it due to the danger of uv damage to your eyes. Place the burning piece of magnesium back in the crucible and let it burn down. Turn of the burner. After the crucible cools off find the new mass. It should be less than the original mass of the crucible and magnesium. However when we performed this experiment the mass was the same. Next take a small amount of distilled water and pour it int the crucible. Check the conductivity of the liquid with a conductivity checker. There should be a small electrical charge.
