Questions
Write a chemical equation for the event.
Iron filings are dropped in aqueous solution of copper sulphate.
Iron dissolved in aqueous solution of copper sulphate.
Explain the following reaction with the balanced equation.
Ferrous dissolved in aqueous solution of copper sulphate.

Solution
More reactive iron pushes copper out of the copper sulphate solution when iron filings are added. Reddish-brown copper metal coats the iron filings, and ferrous sulphate is created as the blue colour of copper sulphate gradually disappears.
\[\ce{Fe_{(s)} + \underset{Blue}{CuSO4_{(aq)}} -> \underset{Colourless}{FeSO4_{(aq)}} + \underset{Copper}{{Cu}_{(s)}}}\]
