Zinc sulfide
Zinc sulfide is white to off-white or light yellow powder. See the light darken. It is stable in dry air, and when it is placed in humid air for a long time or contains moisture, it will gradually oxidize to zinc sulfate. Zinc sulfide is soluble in dilute inorganic acid, soluble in alkali, but insoluble in water. The relative density is 3.98 (α type), (d25) 4.102 (β type). It is irritating.
