Correct Question:
A green coloured substance A is heated strongly and change to brown coloured substance B and smell of burning sulphur is also observed name A and B.
Correct Solution:
The name of compound A is Ferrous Sulphate (FeSO4) and that of B is Ferric oxide (Fe2O3).
- Ferrous sulphate is green in colour and its reaction on heating is given as:
2 FeSO4 → Fe2O3 + SO2 + SO3
- Ferric oxide (Fe2O3) formed in this reaction is brown in colour.
- The smell of this reaction is of burning sulphur.
