Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO 4 (H 2 O) 6. This highly soluble turquoise coloured salt is a common source of the Ni 2+ ion for electroplating .
A binary compound of nickel contains one other element. Substances that contain only nickel atoms are not actually compounds. In a noble gas matrix, nickel can form dimers, a molecule with two nickel atoms: Ni 2. [1] Ni 2 has a bonding energy of 2.07±0.01 eV. For Ni 2 + the bond energy is around 3.3 eV. Nickel dimers and other clusters can ...
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.
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.
The geometry of the nickel(II) ion is square planar. [2] It is surrounded by two equivalents of the conjugate base (dmgH −) of dimethylglyoxime (dmgH 2).The pair of organic ligands are joined through hydrogen bonds to give a macrocyclic ligand.
In chemistry, a salt is a neutral compound composed of cations bound to anions. In general, these salts are ionic compounds which form crystals. They are often soluble in water, where the two ions separate. Salts typically have a high melting point, low hardness, and low compressibility. If molten or dissolved in water, they conduct electricity
The known salts include (NH 4) 2 Ni 2 (SO 4) 3, K 2 Ni 2 (SO 4) 3 and Rb 2 Ni 2 (SO 4) 3, and those of Tl and Cs are predicted to exist. Some minerals are double salts, for example Nickelzippeite Ni 2 (UO 2 ) 6 (SO 4 ) 3 (OH) 10 · 16H 2 O which is isomorphic to cobaltzippeite , magnesiozippeite and zinczippeite , part of the zippeite group.
