Answer» ong>Answer: 1)Action of HEAT on copper sulphate crystals Action of heat on copper sulphate crystalsThe crystals are converted to a powdery substance. The crystals lose their BLUE coloration on further heating. Steaming vapours are produced inside the tube which condense near the mouth of the tube to form a colourless liquid. 2)Action of heat on copper sulphate crystalsThe crystals are converted to a powdery substance. The crystals lose their blue coloration on further heating. Steaming vapours are produced inside the tube which condense near the mouth of the tube to form a colourless liquid.The blue coloured copper sulphate crystals turns white due to the loss of water MOLECULES . When copper sulphate is heated , it looses water molecules and hence it looses blue colour . On heating , FERROUS sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed .
