What will be observed when magnesium is added to iron(II) sulfate solution?

• no visible change

• green solution turns colourless

• green precipitate is formed

• brown solid is formed

• grey metal remains grey

Explain the observation when magnesium is added to copper(II) sulfate solution.

• Mg more reactive than Cu and displace Cu²⁺ from CuSO₄.

• Mg less reactive than Cu and displace Cu from CuSO₄.

• Cu is more reactive than Mg and displace Mg²⁺ from the solution.

• Cu is less reactive than Mg and so is unable to displace Mg.

A displacement reaction will occur when...

• a more reactive metal displaces a less reactive metal from its compound.
• A less reactive metal displaces a more reactive metal from its compound
