Zinc carbonate is the inorganic compound with the formula ZnCO 3. It is a white solid that is insoluble in water. It exists in nature as the mineral smithsonite. It is prepared by treating cold solutions of zinc sulfate with potassium bicarbonate. Upon warming, it converts to basic zinc carbonate (Zn 5 (CO 3) 2 (OH) 6). [6]
Zinc is a strong reducing agent with a standard redox potential of −0.76 V. Pure zinc tarnishes rapidly in air, rapidly forming a passive layer. The composition of this layer can be complex, but one constituent is probably basic zinc carbonate, Zn 5 (OH) 6 CO 3. [8] The reaction of zinc with water is slowed by this passive layer.
2 Zn(OH) 4. the polymeric anion [Zn(OH) 3 −] and its salts, for example NaZn(OH) 3 · H 2 O. [1] an oxide containing zinc and a less electronegative element e.g. Na 2 ZnO 2. [2] In the health supplement industry zincate may also mean a commercially available zinc supplement, typically formulated as zinc sulfate. [citation needed]
Hydrozincite, also known as zinc bloom or marionite, is a white carbonate mineral consisting of Zn 5 (CO 3) 2 6.It is usually found in massive rather than crystalline form.. It occurs as an oxidation product of zinc ores and as post mine incrustations.
Sherritt International is a Canadian resource company, based in Toronto, Ontario. Sherritt is a miner and refiner of nickel and cobalt. Sherritt is also the largest independent energy producer in Cuba. Sherritt’s common shares are listed on the Toronto Stock Exchange under the symbol "S".
Smithsonite, also known as zinc spar, is the mineral form of zinc carbonate (Zn CO 3). Historically, smithsonite was identified with hemimorphite before it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion.
Zinc chloride hydroxide monohydrate or more accurately pentazinc dichloride octahydroxide monohydrate is a zinc hydroxy compound with chemical formula Zn 5 (O H) 8 Cl 2 ·H 2 O. It is often referred to as tetrabasic zinc chloride (TBZC), basic zinc chloride, zinc hydroxychloride, or zinc oxychloride. It is a colorless crystalline solid ...
Zinc carbonate ZnC O 3 or smithsonite and; Zinc silicate Zn 4 Si 2 O 7 (OH) 2 ·H 2 O or hemimorphite. Although chemically and crystallographically quite distinct, the two minerals exhibit similar massive or botryoidal external form [1] [2] and are not readily distinguished without detailed chemical or physical analysis.
