Question

When green coloured ferrous sulphate crystals are heated, the colour of the crystal changes to white because * 1 point It is decomposed to ferric oxide It loses its water of crstallization it forms SO2 it forms SO3​

Answer 1

Answer:

On heating, ferrous sulphate crystals lose water. So their colour changes from light green to white due to the formation of anhydrous ferrous sulphate (FeSO4). When ferrous sulphate is heated, it gives ferric oxide, sulphur dioxide and sulphur trioxide.
