A student performed the experiment of heating ferrous sulphate crystals in a boiling tube. He smell fumes of a pungent gas saw colours of ferrous sulphate disappear Identify the nature of this chemical reaction.

On heating copper powder in air, the surface of copper powder becomes coated with black CuO. How can this black be converted into brown copper? Write chemical equation for the reaction that occurs during the colour change.

A student performed the experiment of heating ferrous sulphate crystals in a boiling tube. He smell fumes of a pungent gas saw colours of ferrous sulphate disappear Why does the colour of crystals disappear?

When conc. H_2SO_4 was added to an unknown salt present in a test tube, a brown gas (A) was evolved. The gas intensified when copper turnings were also added into this test tube. On cooling the gas A changed into a colourless gas (B). Identify the gases (A) and (B).
