Answer 2

Answer:

Here are the equations for the reaction:

magnesium + copper sulfate → magnesium sulfate + copper

Mg + CuSO4 → MgSO4 + Cu

No reaction is seen if you do things the other way round – in other words, if you put copper powder into magnesium sulfate solution. This is because copper is not reactive enough to displace magnesium from magnesium sulfate.
