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.
