Zinc SulfideSodium Nitride, Formula, Chemical Properties, Preparation, Application

Zinc Sulfide

Zinc sulfide is an inorganic compound that has consists the polar covalent bond. It has consists of one zinc atom and one sulfur atom. In the presence of oxidizing agents it decomposed. It can be synthesized when the sulfur and zinc is mixed. In naturally it occurs as the mineral zinc blende. It is known as the sphalerite. Zinc sulfide has possessed high density compared to the water.  The systematic IUPAC name is known as zinc sulfide. The chemical or molecular formula of zinc sulfide is ZnS . it is also known as zincblende or wurtzite.

Structural Formula

This is the structural formula of the zinc sulfide:

Zinc Sulfide

Chemical Formula

The chemical formula of the zinc sulfide is ZnS. It has consists of one zinc atom and one sulfur atom.

How it Can be Produced

When the zinc is reacted with the sulfide in the presence of oxygen it gives the zinc sulfide as the product and oxygen as the byproduct. The zinc ions is the positive and sulfide is the negative ions. While the zinc sulfate is passed over through the sodium or hydrogen sulfide, it will precipitates the insoluble zinc sulfide. The chemical reaction is given below.
