Answer» 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 .
