And alkalies.
Zinc sulfide in acid solubility: Zinc issoluble.
soluble in dilute mineral acids.
Zinc exists primarily in the form sphalerite, a mineral composed of zinc sulfide. It is used in pigments because, although the mineral is typically black, it is actually white due to the impurities. Zinc Sulfide, in dense synthetic forms, can be transparent and serve as a lens for infrared and visible optics.

Is zinc sulfide harmful?
Chronic: Zinc-containing fumes may cause metal fume fever. Sulfides are irritants to the skin. Hydrogen sulfur, if produced, is toxic and highly flammable. The effects include conjunctivitis and headaches.
Is zinc sulfide soluble in water?
Zinc sulfide 4.1 g/mL at 25 degC(lit.) Soluble with acids. Insoluble in Water
Different forms ZnS
ZnS can be found in two primary crystal forms. The duality of these crystals is an example of polymorphism. In both forms, the Zn-S coordination geometry is a tetrahedron. The cubical form is called zinc blend, or sphalerite. The hexagon is also known by the mineral name wurtzite. It can be manufactured synthetically. The transition between sphalerite and wurtzite occurs around 1020degC. The tetragonal crystalline form is called (Zn Hg)S, a chemical compound with the formula (Zn Hg).
Zinc Sulfide (ZnS) is a solid crystal used in optical and semiconductor applications.

How is Zinc Sulfide ZnS produced?
Zinc sulfur is typically made from waste products that are used for other purposes. Sources include pickling liquid, slag and smelters. It can also be a byproduct of the ammonia production from methane. In this case, zinc oxide is used as a solvent to remove hydrogen-sulfur impurities.
Zinc sulfide is used for:
ZnS pigments are used most commonly in paints and rubbers. Lithopone (a mixture of ZnS, barium, and sulfate) is widely used as a pigment in low-gloss enamel paints. ZnS can be used for a variety of electronic and decorative uses because it is phosphorescent.
High-purity zinc sulfide crystal powder is a widely used basic material, especially in high-tech industries such as aerospace, civil defense, and military. It is a very important window for far-infrared imaging and precision guidance using medium-long wave far-infrared, especially in the national defense. Military and other cutting edge technology fields. Zinc Sulfide has the following applications:
The material is luminous.
Zinc Sulfide combined with a tiny amount of an activator suitable for the application has a strong phosphorescence. It is used today in many applications, from cathode-ray tubes to X ray screens, to emit light into dark products. Silver as an activator produces a bright, blue color up to 450 nm. Manganese emits an orange-red light of 590 nm. Copper is able to glow for long periods of time with the familiar dark green glow. In electroluminescent panel, copper-doped sulfide is used ("ZnS+Cu"). The impurities in the material can cause it to glow under blue and ultraviolet light.
Materials that are optically clear
Zinc Sulfide, which transmits visible light wavelengths up to 12 microns in size, is also used for infrared optics. It can either be used flat as an optical lens or shaped like a window. It's made of zinc vapor and hydrogen sulfide to make microchips. It's sold as FLIR Grade (front looking infrared), which is opaque zinc sulfide in a yellowish cream color. By hot isostatic forming (HIPed), it can be turned into a clear form of water called Cleartran. Early commercial forms of the product were sold as Iran-2. However, this name is no longer used.
Pigment
Zinc Sulfide (also known as Statolith) is a common pigment. Combining zinc sulfide with bariumsulfate forms lithopone.
Catalyst
The fine ZnS particles are an effective photocatalyst. They generate hydrogen when illuminated. The synthesis process can introduce sulfur vacancies into ZnS. This slowly turns yellow ZnS to brown powder, and increases photocatalytic activities through increased light absorption.
Zinc Sulfide (ZnS) Powder:
Zinc sulfide (CAS 1314-98-3) is a powder that ranges from white to light yellow or off-white. Watch the color change. Zinc sulfate slowly oxidizes in moist air or in air containing moisture. Soluble in dilute mineral acid, soluble in alkali, insoluble in water. The relative density (a-type), is (d25) 4,102 (b-type). Irritating.
