2 g of ferrous sulphate crystals are heated in a dry boiling tube. Name the type of chemical reaction takes place.

•Take about 2 g ferrous sulphate crystals in a dry bottle tube. • Note the colour of the ferrous sulphate crystals. • Heat the boiling tube over the flame of a burner or spirit lamp as shown in Fig. Observe the colour of the crystals after heating.

2 g of ferrous sulphate crystals are heated in a dry boiling tube. Write the chemical equation for the reaction.

Aim : To study the decomposition of ferrous sulphate on heating Activity: Take approximately 2 g of ferrous sulphate crystals in a dry boiling tube. Heat the boiling tube over the flame of a burner. Observe the colour of the ferrous sulphate crystals carefully during the heating. Observe the colour of the crystals after heating it. What is the colour of crystals of ferrous sulphate ?
