2 has the most ionic character, whereas the others, ZnCl 2, ZnBr 2, and ZnI 2, have relatively low melting points and are considered to have more covalent character. [2] The pnictogenides Zn 3 N 2 (notable for its high melting point [11]), Zn 3 P 2, Zn 3 As 2 and Zn 3 Sb 2, have various applications. [12] Other binary compounds of zinc include ...
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]
The [Zn 2] 2+ ion is implicated by the formation of a yellow diamagnetic glass by dissolving metallic zinc in molten ZnCl 2. [61] The [Zn 2] 2+ core would be analogous to the [Hg 2] 2+ cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric structure. The first zinc(I) compound containing the Zn–Zn bond ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Zinc acetate is a component of some medicines, e.g., lozenges for treating the common cold. [1] Zinc acetate can also be used as a dietary supplement. [2] As an oral daily supplement it is used to inhibit the body's absorption of copper as part of the treatment for Wilson's disease. [3]
The elements of group 12 have an oxidation state of +2 in which the ions have the rather stable d 10 electronic configuration, with a full sub-shell. However, mercury can easily be reduced to the +1 oxidation state; usually, as in the ion Hg 2+ 2, two mercury(I) ions come together to form a metal-metal bond and a diamagnetic species. [24]
The Colts are 2-4 in games he has played. Entering Week 11, the Colts are 4-6 and second in the AFC South, two games behind the first-place Houston Texans and just outside the AFC playoff picture.
Zinc nitrate is an inorganic chemical compound with the formula Zn(NO 3) 2. This colorless, crystalline salt is highly deliquescent. It is typically encountered as a hexahydrate Zn(NO 3) 2 ·6H 2 O. It is soluble in both water and alcohol.
