**Step-by-Step Text Solution:** 1. **Heating Ferrous Sulphate Crystals:** When 2 g of ferrous sulphate crystals (FeSO4·7H2O) are heated in a dry boiling tube, the first observation is that the crystals will lose their water of crystallization. This process is called dehydration. 2. **Color Change:** Initially, ferrous sulphate crystals are green in color. Upon heating, they will change color due to the loss of water. The crystals will turn into a white or light brown powder, indicating the removal of water molecules. ...
