A solution of CuSO4 was kept in an iron pot. After few days the iron pot was found to have a number of holes in it. Explain the reason in terms of reactivity. Write the equation of the reaction involved.

We know that iron is more reactive than copper. Hence, iron displaced copper from copper sulphate solution. This reaction is called displacement reaction. Due to displacement, there is formation of holes in the iron pot. The following equation shows this reaction.


CuSO4 + Fe → FeSO4 + Cu

A metal M does not liberate hydrogen from acids but reacts with oxygen to give a black colour product. Identify M and black coloured product and also explain the reaction of M with oxygen.

An element forms an oxide A2O3 which is acidic in nature. Identify A as a metal or non-metal.

 59

A non-metal A which is the largest constituent of air, when heated with H2 in 1:3 ratio in the presence of catalyst (Fe) gives a gas B. On heating with O2 it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D which acts as a strong oxidising agent.

(a) Identify A, B, C and D.


(b) To which group of periodic table does this non-metal belong?
