What is observed after about 1 hour of adding the strips of copper and aluminium separately to ferrous sulphate solution filled in two beakers ? Name the reaction if any change in colour is noticed. Also, write chemical equation for the reaction.
Cu(s) + FeSO4(aq) → No change will take place .
Copper is less reactive then Fe so, Cu cannot displace iron from ferrous sulphate solution
* No reaction will take place.
2Al(s) + 3FeSO4(aq) → Al2(SO4)3 + 3Fe(s) (Displacement reaction)
* When Al is added to a FeSO4 (aq) solution , the freen colour of FeSO4(aq) disappears and the Fe is seen setting down as the reaction accurs Al being higher in reacting series displace the Fe in FeSO4 .
