As a supplement it is used to treat zinc deficiency and to prevent the condition in those at high risk. It has the formula Zn SO 4 as well as any of three hydrates. It was historically known as "white vitriol ". All of the various forms are colourless solids.

The heptahydrate form is commonly encountered. In medicine it is used together with oral rehydration therapy ORT and an astringent. The hydrates, especially the heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. It is also used as an electrolyte for zinc electroplatingas a mordant in dyeing, and as a preservative for skins and leather. Zinc sulfate is used to supply zinc in animal feeds, fertilizers, toothpaste, and agricultural sprays.

Zinc sulfate, like many zinc compounds, can be used to control moss growth on roofs. Zinc sulfate can be used to supplement zinc in the brewing process.

Zinc is a necessary nutrient for optimal yeast health and performance, although it is not a necessary supplement for low-gravity beers, as the grains commonly used in brewing already provide adequate zinc. It is a more common practice when pushing yeast to their limit by increasing alcohol content beyond their comfort zone. Before modern stainless steel, brew Kettles, fermenting vessels and after wood, zinc was slowly leached by the use of copper kettles.

A modern copper immersion chiller is speculated to provide trace elements of zinc; thus care must be taken when adding supplemental zinc so as not to cause excess. Side effects include " Excess zinc can also cause soapy or goaty flavors.

Zinc sulfate powder is an eye irritant. Ingestion of trace amounts is considered safe, and zinc sulfate is added to animal feed as a source of essential zinc, at rates of up to several hundred milligrams per kilogram of feed. Zinc sulfate is produced by treating virtually any zinc-containing material metal, minerals, oxides with sulfuric acid. Specific reactions include the reaction of the metal with aqueous sulfuric acid :.

Pharmaceutical-grade zinc sulfate is produced by treating high-purity zinc oxide with sulfuric acid:. In aqueous solution, all forms of zinc sulfate behave identically.

ZnO is a white powder that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers, plastics, ceramics, glass, cement, lubricants, [10] paints, ointments, adhesives, sealants, pigments, foodsbatteries, ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as the mineral zincitemost zinc oxide is produced synthetically.

The native doping of the semiconductor due to oxygen vacancies or zinc interstitials is n-type. Those properties are valuable in emerging applications for: transparent electrodes in liquid crystal displaysenergy-saving or heat-protecting windows, and electronics as thin-film transistors and light-emitting diodes. Pure ZnO is a white powder, but in nature it occurs as the rare mineral zincitewhich usually contains manganese and other impurities that confer a yellow to red color.

Crystalline zinc oxide is thermochromicchanging from white to yellow when heated in air and reverting to white on cooling. Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acidssuch as hydrochloric acid: [15]. ZnO reacts slowly with fatty acids in oils to produce the corresponding carboxylatessuch as oleate or stearate.

ZnO forms cement-like products when mixed with a strong aqueous solution of zinc chloride and these are best described as zinc hydroxy chlorides. ZnO also forms cement-like material when treated with phosphoric acid ; related materials are used in dentistry. Zinc oxide can react violently with aluminium and magnesium powders, with chlorinated rubber and linseed oil on heating causing fire and explosion hazard.

It reacts with hydrogen sulfide to give zinc sulfide.

This reaction is used commercially. Zinc oxide crystallizes in two main formshexagonal wurtzite [22] and cubic zincblende. The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing ZnO on substrates with cubic lattice structure. In both cases, the zinc and oxide centers are tetrahedralthe most characteristic geometry for Zn II.

ZnO converts to the rocksalt motif at relatively high pressures about 10 GPa. Hexagonal and zincblende polymorphs have no inversion symmetry reflection of a crystal relative to any given point does not transform it into itself. This and other lattice symmetry properties result in piezoelectricity of the hexagonal and zincblende ZnO, and pyroelectricity of hexagonal ZnO. This property accounts for the preferential formation of wurtzite rather than zinc blende structure, [25] as well as the strong piezoelectricity of ZnO.

Because of the polar Zn-O bonds, zinc and oxygen planes are electrically charged. To maintain electrical neutrality, those planes reconstruct at atomic level in most relative materials, but not in ZnO — its surfaces are atomically flat, stable and exhibit no reconstruction.

This anomaly of ZnO is not fully explained. ZnO is a relatively soft material with approximate hardness of 4. The high heat capacity and heat conductivity, low thermal expansion and high melting temperature of ZnO are beneficial for ceramics.

Among the tetrahedrally bonded semiconductors, it has been stated that ZnO has the highest piezoelectric tensor, or at least one comparable to that of GaN and AlN. Advantages associated with a large band gap include higher breakdown voltages, ability to sustain large electric fields, lower electronic noiseand high-temperature and high-power operation. Most ZnO has n -type character, even in the absence of intentional doping. Nonstoichiometry is typically the origin of n-type character, but the subject remains controversial.

Reliable p-type doping of ZnO remains difficult. This problem originates from low solubility of p-type dopants and their compensation by abundant n-type impurities. This problem is observed with GaN and ZnSe. Measurement of p-type in "intrinsically" n-type material is complicated by the inhomogeneity of samples.

Current limitations to p-doping limit electronic and optoelectronic applications of ZnO, which usually require junctions of n-type and p-type material. However, many of these form deep acceptors and do not produce significant p-type conduction at room temperature.

ZnO discs, acting as a varistorare the active material in most surge arresters.Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below. More info about absorbents, including situations to watch out for What is this information?
