zinc sulfate
zinc sulfate, chemical compound ZnSO4, a very water soluble, transparent, colorless, crystalline compound. It is commonly used as the heptahydrate, ZnSO4·7H2O, and is commonly called white vitriol; it occurs naturally as the mineral goslarite, and can be prepared by reacting zinc with sulfuric acid. It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays; in making lithopone; in coagulation baths for rayon; in electrolyte for zinc plating; as a mordant in dyeing; as a preservative for skins and leather; and in medicine as an astringent and emitic.Zinc Sulfate ZnSO4, a colorless crystalline compound, with a density of 3.74 g/cm3. Its solubility in water is 29.4 percent at O°C and 37.7 percent at 99°C. At temperatures below 38.8°C, ZnSO4·7H2O (zinc vitriol) crystallizes from solution, and between 38.8°C and 70°C, ZnSO4·6H2O. The monohydrate ZnSO4H2O forms above 70°C, which dehydrates at 238°C. Between 600°C and 900°C, zinc sulfate decomposes into ZnO and SO2. Weak solutions of zinc sulfate become turbid upon hydrolysis as a result of the precipitation of 3Zn(OH)2·ZnSO4·4H2O. Zinc vitriol is obtained by evaporation and crystallization from solutions, usually as a by-product in the production of zinc. It is used in the production of viscoses, mineral pigments, and glazes. In metallurgy it is used as a flotation reagent. It is also used in medicine.

zinc [zingk] a chemical element, atomic number 30, atomic weight 65.37, symbol Zn. (See Appendix 6.) It is a trace element in the diet, a component of several enzymes, including DNA and RNA polymerases and carbonic anhydrase. It is abundant in red meat, shellfish, liver, peas, lentils, beans, and rice. A well-balanced diet assures adequate intake of zinc. Those who may suffer from zinc deficiency include persons on a strictly vegetarian diet and those who are on a high-fiber diet. In the latter case, the zinc is bound to the fiber and is eliminated in the feces without having been absorbed through the intestinal wall. Poor absorption of zinc also can occur in persons with chronic and severe bowel disease. The recommended daily intake is 12–15 mg for an adult. A severe deficiency of zinc can retard growth in children, cause a low sperm count in adult males, and retard wound healing. Signs of a deficiency include anorexia and a diminished sense of taste. An excessive intake of zinc (usually in those who work with the metal or breathe its fumes) can either cause pneumoconiosis or interfere with the body's use of copper and other trace elements, producing diarrhea, nausea, vomiting, and other signs of intestinal irritation.zinc acetate a salt used as an astringent and styptic.zinc chloride a salt used as a nutritional supplement in total parenteral nutrition and applied topically as an astringent and a desensitizer for dentin.zinc oxide a topical astringent and skin protectant; also a sunscreen.zinc stearate a powder of zinc in a compound with stearic and palmitic acids; used as a water-repellent skin protectant in dermatoses.zinc sulfate a topical astringent for mucous membranes, especially those of the eye.zinc undecylenate the zinc salt of undecylenic acid; it is a topical antifungal.zinc sul·fateused as a local astringent in the treatment of gonorrhea, indolent ulcers, conjunctivitis, and various skin diseases, and internally as an emetic.zinc sulfaten.
