A green coloured solid compound ̳X‘, gets oxidized to reddish brown solid in presence of air.
̳X‘ on heating gives brown coloured solid ̳Y‘ and two pungent smelling gases ̳A‘ and ̳B‘.
̳A‘ turns acidified potassium dichromate solution green. Name ̳X‘, ̳Y‘, ̳A‘ , ̳B‘ and type of
Reaction.
(a) CuSO 4 , CuO, SO 2 , SO 3 , decomposition
(b) FeSO 4 , Fe, SO 2 , SO 3 , decomposition
(c) FeSO 4 , Fe 2 O 3, SO 2 , SO 3 , decomposition
(d) FeSO 4 , Fe 2 O 3 , SO 3 , SO 2 , decomposition
