Question

what happened when (i) baking soda is heated (ii) blue coloured copper sulphate crystals are heated (iii) water is added to lime

Answer 1

1 ) When baking soda is heated, it easily loses carbon dioxide and carbon dioxide makes bubbles and this creates channels, which is what gives baked goods a fluffy and light texture.
2)When Copper sulphate is heated it loses water molecules and hence it loses it blue colour.
3)When water is added to lime formation of slaked lime takes place.
