(f) The substance that can remove hydrogen and oxygen atoms in the ratio of 2 : 1 (in the form of water) from the compounds. 3. Water of crystallization are the molecules of water that are incorporated into some salt crystals when they are crystallised out of water. (a) Blue vitriol (b) Baking soda (c) Washing soda (d) Gypsum (b) Baking soda. It is crystalline and contains five molecules of water of crystallization. It is mainly used by doctors as a plaster for setting the fractured bones in the right position. (b) Washing soda is exposed to air ? (i) It changes into white powder due to loss of water of crystallisation. Antiseptic agent 2. 2. About 3% of these are Sulphate, 0% are Oxide. Vitriol, any of certain hydrated sulfates or sulfuric acid.Most of the vitriols have important and varied industrial uses. On heating CuSO 4.5H 2 O loses its water of crystallization and decomposes at 720 o C to give cupric oxide and sulphur trioxide. The percentage of water of crystallisation of a sample of blue vitriol is, → 249.55×18 ×100= 36.07 %. When a compound loses its water of crystallisation on exposure to dry air. Which one of the following salts does not con-tain water of crystallisation? Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5.
