Q9 (b). What happens when
Iron nails are placed in copper sulphate solution?
Write word equations of the reactions involved.
We know that a more reactive metal displaces a less reactive metal from its salt solution. When iron nails are placed in copper sulphate solution, iron being more reactive than copper, displaces copper and forms ferrous(iron) sulphate salt and copper deposits on the iron nails. The blue colour solution turns into green.
