Magnesium Lab Thomas Knight

Thomas Knight 1/13/12 Magnesium Lab




Materials

• Crucible



• 2 equal length strips of magnesium



• Scale



• Clay Triangle



• Tripod



• Bunsen Burner
  

Safety Concerns

1. Wear GOGGLES

2. NO baggy clothes

3. Keep your hair pulled back.

4. NO open toed shoes.




Procedure

1. Cut 2 strips of magnesium

2. Twist them together

3. Mass the empty crucible

4. Zero the scale and mass the piece of magnesium. Record the mass.

5. Remove the magnesium

6. Put the crucible onto the clay triangle on the tripod

7. Light the bunson burner

8. Put the strip of magnesium into the flame, it will eventually light.

9. DO NOT LOOK directly into the light when the magnesium lights.

10. Look out of the corner of your eye and drop the burning magnesium into the crucible.

11. Let it burn

12. Let the magnesium and the crucible cool.

13. When cooled, put the crucible, with the magnesium on the scale and mass it.

14. Record the mass.

Data Collected

• Empty Crucible- 34.58 grams




• Unburned Magnesium- 0.09 grams
  




• Burned Magnesium- 1.03 grams

Errors
I really don't know whether i was supposed to mass the crucible with the lid on or off. I guess that my biggest error is that i didn't ask any questions. I just did what I thought was right.




Analysis. Page 233 1-7 1-2



1. Empty Crucible- 34.58 grams



Crucible and Magnesium before heating- 34.67 grams



Magnesium- 0.9 grams



Crucible and Magnesium after heating- 35.61



Magnesium after heating- 1.03 grams







2. Since it gave off heat it would be exothermic.







3.







4. MgO and Mg2N2







5. Magnesium and Qxygen.







6. It conducted an electric current, which shows that the compund is Ionic.




7. Not enough time for the oxygen to mix into the crucible

Real World Chemistry

1. Yes it is a component.

2. Magnesium Hydroxide
