ZINC CHLORIDE (ZnCl2)
[CODE NO. 3376]
Zinc is in Group II B of the periodic table and exhibits a valence of +2 in all its compounds. Being high on the electromotive series, Zinc form quite stable compounds. Bonding in Zinc compounds tends to be covalent, with strongly electropositive elements, eg chlorine, the bond is more ionic.
Zinc chloride is one of the important zinc componds. It is stable in the vapour phase upto 900oC. It is very hygroscopic, extremely water soluble, and soluble in organic liquids such as alcohols, esters, ketones,ethers, amides and mitrictes. Hydrates with 1, 1.5, 2.5, 3, and 4 molecules of water have been identified and great care must be expressed to avoid hydration of the anhydrous form.
Aqueous solution of zinc chloride are acidic (pH=1.O for 6 m ),and when partially neutralized form slighly soluble basic chlorides eg. Zncl2 and 4 Zn( ch)2 and Zn(ch)cl many other basic chlorides have been reported.
Zinc Chloride (Zn Cl2) is available as white, crystalline powder, odourless, moulded in pencils or porcelains like mass.
It is one of the most soluble inorganic substances 432gm dissolving in 100 ml of water at 25o, and 635 gm at 100oC. It is also quite soluble in organic solvents containing oxygen or nitrogen.
It is difficult to remove the last traces of water from the solid for it is highly hygroscopic. It is surprising that the degree of hydrolysis of aqueous solution of Zinc Chloride at moderate dilution is very small. Its aqueous solution is acidic. It has been called "butter of zinc" because of its formation of a white semi solid mass on evaporation.
Zinc Chloride is obtained by heating zinc with dry chlorine gas, by the action of hydrochloric acid on Zinc Oxide, or by heating a mixture of Zinc Sulphate and Sodium Chloride.
It is economical to manufacture zinc chloride from secondary Zinc sources as Zinc dross, sal skimming, etc. The zinc dross is treated with some what less than required quantity of hydrochloric acid and the clear liquid is filtered off. The oxides dross residue is then treated with chlorine and the resultant zinc chloride is leached off and added to the first filtrate. The clear liquid is evaporated to the desired stage
Zinc chloride is an industrially important compound of Zinc. In aqueous solution, it may be used alone or in combination with phenol or sodium chromate as a wood preservative for railway sleepers poles for communication lines, etc. and for fire proofing timber.
In the textile industry,Zinc chloride is used for crimping wool,cotton and silk. It is used as carbonizing agent in treating wool and for fire proofing woolen goods. In the rayon industry, Zinc Chloride is used as catalyst or process material for miscellaneous purposes.
