Aqueous solutions of nickel sulfate react with sodium carbonate to precipitate nickel carbonate, a precursor to nickel-based catalysts and pigments. [6] Addition of ammonium sulfate to concentrated aqueous solutions of nickel sulfate precipitates Ni(NH 4) 2 (SO 4) 2 ·6H 2 O. This blue-coloured solid is analogous to Mohr's salt, Fe(NH 4) 2 (SO ...
As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2] With sodium, the double sulfate is nickelblödite Na 2 Ni(SO 4) 2 · 4 H 2 O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form. [3]
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Nickel carbonates are hydrolyzed upon contact with aqueous acids to give solutions containing the ion [Ni(H 2 O) 6] 2+, liberating water and carbon dioxide in the process. Calcining (heating to drive off CO 2 and water) of these carbonates gives nickel(II) oxide: NiCO 3 → NiO + CO 2. The nature of the resulting oxide depends on the nature of ...
Basic nickel carbonate, zaratite, with the formula Ni 4 CO 3 (OH) 6 (H 2 O) 4, is produced when alkali carbonates are added to a nickel solution. Nickel phosphate, Ni 3 (PO 4) 2 · 7 H 2 O is also insoluble. [1] A number of other phosphates have been made, including nanoporous substances resembling zeolites named with "Versailles Santa Barbara ...
The structure of Ni(SCN) 2 was determined via single-crystal X-ray diffraction and consists of two-dimensional sheets held together through Van der Waals forces. It belongs to mercury thiocyanate structure-type and can be considered a distorted form of the NiBr 2 (CdI 2) structure. Each nickel is octahedrally coordinated by four sulfurs and two ...
Ferric subsulfate solution is a styptic or hemostatic agent used after superficial skin biopsies. [1] Ferric subsulfate solution is also known as basic ferric sulfate solution or Monsel's solution. It has a recognised formula published in United States Pharmacopeia 29.
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.
