Zinc Sulfide Formula

Zinc Sulfide Formula

Here we will discuss the formula of Zinc Sulfide and the various uses of Zinc Sulfide in our day-to-day life. 

Zinc sulfide is a yellowish-white coloured crystal and is crystalline. Zinc sulfide can also be named zinc blend of Wurtzite. The structure of the zinc blend is not a complex one. Rather than its simple structure in which the zinc metal and the sulfur atoms are bonded to each other with the help of polar covalent bonds.

The molecular formula of zinc sulfide is named ZnS. The structural formula of zinc sulfide is :

                              S———-Zn

The sulfur atom binds to the zinc atoms with the help of polar covalent bonds.

This is also known as zinc blend. The zinc metal occurs naturally as zinc blend, which is the mineral ore and is also used for extraction of zinc metal from this. Sphalerite is also the name which is given to Zinc sulfide. A basic procedure for the synthesis of ZnS is by the combustion of  Sulfur and zinc mixture. 

Characteristics of ZnS

• The chemical formula of zinc sulfide is ZnS

• The melting point of zinc sulfide is 1850°C

• The molecular weight of zinc sulfide is 97.474g/mol

• The boiling point of zinc sulfide is 1935°C

• The density of zinc sulfide is 4090 g/ml

The compound zinc sulfide can decompose easily when an oxidizing agent is present. Even in the presence of acids, this compound decomposes. The compound zinc sulfide does not pose any harm to living beings, but it possesses a freight and is hazardous to the environment. Zinc sulfide affects the groundwater system as it soaks into the soil and gets mixed with the underground water and contaminates it and makes it unsuitable for public use.

Uses of Zinc Sulfide

The compound zinc sulfide is used as a luminescent material. It has been used in most of the blow in the dark toys or objects because zinc chloride exhibits the property of intense Phosphorescence, which makes it suitable to use in the cathode ray tubes. In the presence of heat, the finely divided zinc sulfide powder will act as a photocatalyst and result in the production of hydrogen gas from water.
