Anhydrous cobalt(II) fluoride. Cobalt(II) fluoride is a chemical compound with the formula (CoF 2).It is a pink crystalline solid compound [1] [2] which is antiferromagnetic at low temperatures (T N =37.7 K) [3] The formula is given for both the red tetragonal crystal, (CoF 2), and the tetrahydrate red orthogonal crystal, (CoF 2 ·4H 2 O).
Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3 ) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [ 12 ] and its molecule contains cobalt(II) hydrated ions ([Co(H 2 O) 6 ] 2+ ) and free nitrate ions.

Azoth – initially this referred to a supposed universal solvent but later became another name for Mercury. Bitumen – highly viscous liquid or semi-solid form of petroleum. Blende; Brimstone – sulfur; Flowers of sulfur – formed by distilling sulfur. Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash.
Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. Thus, KCH 3 CO 2 can be named as potassium acetate or as potassium ethanoate.
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Articles about functional groups should use the name most commonly used to refer to the group in reliable sources (generally, the name of the corresponding radical) followed by the word "group", e.g. alkyl group, carboxyl group, phenyl group, carbonyl group, trimethylsilyl group, triflyl group. In many cases, the compound or compound class and ...
Typically these have a metal, such as a copper ion, in the center and a nonmetals atom, such as the nitrogen in an ammonia molecule or oxygen in water in a water molecule, forms a dative bond to the metal center, e.g. tetraamminecopper(II) sulfate [Cu(NH 3) 4]SO 4 ·H 2 O. The metal is known as a "metal center" and the substance that ...
p-Toluenesulfonic acid is a comparatively strong acid used in organic chemistry often because it is able to dissolve in the organic reaction solvent. Exceptions to these solubility characteristics exist in the presence of other substituents that affect the polarity of the compound.
