To study the chemical reaction of an iron nail with aqueous copper sulphate. solution; and to study the burning of magnesium ribbon in air. (a) Chemical reaction of iron nail with copper sulphate solution in water. THEORY. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Iron is placed above copper in the activity series. Elements placed above in this series are more reactive than those placed below them. Thus iron is more reactive than copper. In this reaction, metallic iron is converted into ferrous ion (Fe2+) and
