The Production Process of Zinc Chloride:

The reaction of zinc and hydrochloric acid is used to produce anhydrous zinc chloride. During this reaction, ZnCl2 and hydrogen gas are produced. The chemical equation of the reaction is as follows:

Zn(s) + 2 HCl → ZnCl₂ + H₂(g)

Its hydrated form and an aqueous solution of zinc chloride can be prepared by reacting zinc metal and various salts of zinc (such as zinc carbonate, zinc oxide, and zinc sulfide) with hydrochloric acid.

ZnS + 2 HCl + 4 H₂O → ZnCl₂(H₂O)₄ + H₂S

Commercial samples of zinc chloride contain water and products from the hydrolysis of impurities. Some of these impurities can be obtained by recrystallization from hot dioxane.

Zinc Chloride Uses:

Zinc chloride is used in various industries. Important applications of this material can be mentioned as follows:

As a Lewis acid used in laboratory syntheses
In welding as welding wire
As an electrolyte in solar cells
To separate oil from water and reduce the stability of oil in water
It is one of the important elements in plant growth
In the paint industry as a color stabilizer
One of the alternative treatments for skin cancer
In the production and protection of wood and adhesives
Production of ion-exchange resin

Zinc Chloride in Metallurgy and Welding:

Due to the ability of zinc chloride to attack metal oxides, this material is used as a flux or flux in metallurgy and soldering. In addition, this material is also used in galvanized welds and coatings.

The Role of Zinc Chloride in Wood and Adhesive:

One of the uses of chloride is its use in the adhesive and wood industry. This material is useful for the production and preservation of adhesive and is also used in wood impregnation. Together with sodium dichromate, zinc chloride helps preserve the wood.
