**Step-by-Step Solution:** **(i) Color of Ferrous Sulphate Crystals:** - Before heating, ferrous sulphate crystals (FeSO₄·7H₂O) are typically green in color. - After heating, the crystals lose water and turn into anhydrous ferrous sulphate (FeSO₄), which is a white or pale yellow color. **(ii) Gases Produced During Heating:** - When ferrous sulphate is heated, it decomposes and produces sulfur dioxide (SO₂) and sulfur trioxide (SO₃) gases. ...
