Zinc Chloride Uses

Introduction to zinc chloride uses:
Zinc chloride (ZnCl2) is a white, granular powder, which is formed by heating zinc sulphate with calcium chloride, or the releasing of zinc oxide or zinc in hydrochloric acid. Anhydrous zinc chloride is whitish, translucent and has a specific gravity of 2.75. It melts at about 318°C. It is very hygroscopic and very soluble in alcohol.  Having problem with Empirical Formula of Copper Chloride keep reading my upcoming posts, i will try to help you.

zinc chloride has a burning taste, and is highly corrosive. The concentrated aqueous solutions of zinc chloride have the property of dissolving starch, silk and cellulose. They can not be filtered through standard filter paper.

Zinc chloride is an ionic salt, which still has a covalent character. It is highlighted by its relatively low melting temperature (275 ° C) and high solubility in solvents such as ether. It behaves as a Lewis acid (moderate), and zinc chloride solutions have a pH of 4. When heated in a hydrated form, it hydrolyzes to form zinc chloride. Let us see the uses of zinc chloride.


Uses of zinc chloride


zinc chloride is used to impregnate wood for the preservation of animal substances.

It is used in the refining of oil, in the preparation of parchment paper, ether (ether), stearic acid.

Zinc chloride is mainly used for welding, because of its ability to dissolve metal oxides when it is in the molten state. This property can also be used in cement based on magnesium oxide for dental prostheses.

ZnCl2 is also used as a fireproofing agent and as etchant of metals.

It is also used in dyeing, as a mordant for aniline blue, for pickling and dyeing of brass.

It is used to glue the paper pulp, for disinfecting

In chemical works as dehydrating agent

In medicine as a caustic, a concentrated solution is used for uniform heating of vessels on a certain higher temperature.

Is this topic Titration Equation hard for you? Watch out for my coming posts.

Other uses of zinc chloride


Zinc chloride is also used in electroplating and in the production of batteries.

In the laboratory,  zinc chloride is used as Lewis acid moderate.
