A solution of copper sulphate was placed on a spotting tile and magnesium powder was added. Over ten minutes, the solution fizzed and turned colorless as a brown solid formed at the bottom, indicating a replacement reaction between the magnesium and copper sulphate that produced magnesium sulphate and copper. The word equation summarizing the reaction is: copper sulphate + magnesium → magnesium sulphate + copper.

1. A teat pipette is used to fill a dimple on a spotting tile with a solution of copper sulphate.

2. A small amount of magnesium powder is added to the solution.

3. For the next ten minutes the spotting tile is observed for any signs of a reaction.

4. There is a fizzing The solution turns from blue to colourless A brown solid gathers at the bottom of the solution

5. Mg Reaction Cu Sulphate

6. Cu Mg Sulphate

7. Cu Mg Sulphate

8. Cu Mg Sulphate

9. Cu Mg Sulphate

10. Cu Mg Sulphate

11. Cu Mg Sulphate

12. Cu Magnesium is a more reactive metal than copper. The magnesium grabs the sulphate from the copper. Mg Sulphate

13. Cu The magnesium has pushed out copper from its compound. Magnesium has displaced the copper. Mg Sulphate
