These sulfides are relatively inert, dissolve into acid, and are insoluble in water and alkalis. Zinc sulfide causes flaming decomp /of hydrazinium nitrate / above the melting point (70 °C). / Hydrazinium nitrate: alone, etc/ The reaction between iodine monochloride and zinc sulfide is vigorous. / Iodine monochloride: cadmium sulfide. Some inorganics, such as silver-activated zinc sulfide, are suitable scintillators but cannot be grown in optical-quality large crystals. As a result, their use is limited to thin polycrystalline layers known as phosphor screens. Zinc sulfide appears as a yellowish-white powder in a liquid. Insoluble in water and denser than water. The primary hazard is to the environment. Immediate steps should be taken to limit the spread of the climate. Quickly penetrates the soil to contaminate groundwater and nearby waterways. WHITE-TO-YELLOW CRYSTALS OR POWDER.
Since zinc sulfide is insoluble in water, it can also be produced in a precipitation reaction. Solutions containing Zn 2+ salts readily form a precipitate ZnS in the presence of sulfide ions (e.g., from H 2 S ). This reaction is the basis of a gravimetric analysis for zinc. Wurtzite, the less common polymorph of zinc sulfide ZnS, exists in two primary crystalline forms, and this dualism is often a salient example of polymorphism. In each form, the coordination geometry at Zn and S is tetrahedral. The more stable cubic form is also known as zinc blende or sphalerite.
