This is because the water molecules are lost Haseena Vannanchalil answered this. copper sulphate crystals( Cu SO4.5H2O) seem to be dry contain water of crystallisation .Different crucibles are to be employed when heating of solution and igniting of materials are to be It is. much heavier than the air and may be passed through a glass tube to the bottle. If we. In the laboratory method, a mixture of sodium nitrate and. concentrated sulphuric acid is heated in a glass...

Heat to boiling and add over forty minutes, as a vapor, 80 g DEA dried (e.g., with Na wire). The residue can be distilled (120-140/12) and redistilled (123-4/12) to give 100 g N,N-diethylacetoacetamide (I). 15.7 g (I) in 80 ml CHCl3 and add dropwise 16 g Br2 in 10 ml CHCl3. first at the place when there is a suicide, a road accident, or a fire.

Results. A light blue precipitate forms when sodium carbonate reacts with copper(II) chloride. No precipitate forms when sodium sulphate reacts with copper(II) chloride. The solution is light blue.

Take about 2g of ferrous sulphate crystals in a dry boiling tube and note the colour of the crystals. Hold the boiling tube with a test tube holder and On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white.
