Question

action of jeat on gerrous sulphate crystales​

Answer 1

On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On furtherheating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).

Answer 2

On heating ferrous sulphate it decomposes into ferric oxide Fe2O3 (residue) which is red in colour. When ferrous sulphate crystals are heated, the residue obtained in test tube is red colour.......
