Magnesium lab

Saftey:

• Hair pulled back
• Saftey glasses on

• Make sure not to look directly at the magnesium strip while burning because the light is very bright and could damage eyes

Materials:

• Magnesium strip
• crucible
• ring stand and ring
• clay triangle
• bunsen burner
• stirring rod
• tongs
• balance
• distilled water
• conductivity tester

Procedure:

• Place the ring on the stand about 7 cm above the bunsen burner, and then place the clay triangle on the ring stand
• record the mass of the crucible and then zero it out and measure the amount of magnesium you would like to burn
• Place the curcible on the clay ring and heat the crucible with the bunsen burner flame
• the magnesium should light in the crucible, but if not take the piece of magnesium and light it in the bunsen burner flame and once it lights with white light (do not look dierectly at the light) place it back in to the crucible and let the rest of the magnesium burn
• once the crucible is cool place it on the balance and record your data
• then add 5ml of distilled water to the crucible and stir together with a stiring rod
• check the mixture with a conductivity checker ( you will see that the christmas lights can light without touching each other
• Record your results

Results:

Trial 1:

Mass of magnesium: .17g

Mass of Magnesium after burning: .22g

Trial 2:

Mass of Magnesium: .10g

Mass of Magnesium after burning: .23g

The magnesium also conducts electricity after it has been burned.

Questions:

1. Mass of magnesium before was .17g and after the magnesium was burned its mass was .22g. The difference between before and after was .05g.


2. Kinetic energy was released by the product because it gave of heat and light.
3. The magnesium reacts with certain air components because when the magnesium was lit the oxygen was lit making the magnesium react with the little amount of oxygen.
4. Magnesium oxide , Magnesium3 nitride2.
5. After the magnesium was completely burned all that was left was white leaving the product formed from oxygen and magnesium.
6. Yes, there was an electric current conducted with the magnesium compounds. no, nothing showed that the compounds were ionic.
7. incorrect measurement, or you didn't let the magnesium completely melt.
8. Magnesium is the fourth most abundant mineral in the body and makes up 50% of the bodies bones and cells. Magnesium is very important for your physical and mental health and can be listed in many different types of vitamins and minerals.
9. In medicine Mg(OH)2 is used for heartburn relief and stomach aches and is also used for a short term laxative. Popular names include, magnesium hydroxide or milk of magnesium.
