A Displacement ReactionA Displacement ReactionMagnesium and Copper SulfateMagnesium and Copper Sulfate

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

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

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

• There is a fizzing• The solution turns

from blue to colourless • A brown solid gathers

at the bottom of the solution
