In chemistry experiment a student by mistake put some magnesium strip in blue coloured copper sulphate solution what change will he observ in colour of the solution.write the reaction also?

When a magnesium strip is added to a blue copper sulfate solution, a chemical reaction occurs, resulting in the displacement of copper by magnesium. The solution will change from blue to colorless as the copper ions are reduced to solid copper, which precipitates out of the solution. The balanced chemical reaction for this process is:

[ \text{Mg (s)} + \text{CuSO}_4 \text{(aq)} \rightarrow \text{MgSO}_4 \text{(aq)} + \text{Cu (s)} ]

This shows magnesium displacing copper from copper sulfate.
