Zinc Sulfide Formula

Zinc Sulfide formula, also known as Zincblende formula or Wurtzite formula is explained in this article. The structure of Zincblende is simple and consists of the zinc metal-sulfur atom attached to each other via a polar covalent bond. The molecular or chemical formula of Zinc Sulfide is ZnS.

It is obtained as a white or yellowish-white crystal. The sphalerite occurs as a greyish white crystal. ZnS is insoluble in water as well as denser than water. Naturally, it occurs as the mineral zinc blende which is also known as sphalerite. It is a mixture of zinc sulfide and iron. ZnS can be synthesized by the combustion of a mixture of sulfur and zinc. Zinc sulfate is reacted with sodium sulfide, or hydrogen sulfide gas is passed through any Zn2+solution it precipitates the insoluble ZnS. Due to its luminescent property, it has wide applications.
