This page looks at some aspects of cobalt chemistry required for UK A' level exams. These are mainly summarised from elsewhere on the site, with links available to more detailed explanations. Reactions of cobalt(II) ions in solution. The simplest ion that cobalt forms in solution is the pink hexaaquacobalt(II) ion - [Co(H 2 O) 6] 2+.
The chemical formula for cobalt is its chemical symbol, Co. Since cobalt is a pure element, its chemical formula is identical to its chemical symbol. Cobalt is the 27th member of the periodic table and is assigned the chemical symbol Co.
Aug 13, 2019· Despite the many uses for cobalt metal, cobalt's primary applications are in the chemical sector, which accounts for about half of the total global demand. Cobalt chemicals are used in the metallic cathodes of rechargeable batteries, as well as in petrochemical catalysts, ceramic pigments, and glass decolorizers.

Cobalt does not react readily with air. Upon heating the oxide Co 3 O 4 is formed, and if the reaction is carried out above 900°C, the result is cobalt(II) oxide, CoO. 3 Co (s) + 4 O 2 (g) 2 Co 3 O 4 (s) 2 Co (s) + O 2 (g) 2 CoO (s) Cobalt does not react directly with nitrogen, N 2.
For each compound, a formal oxidation number for cobalt is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only.
Erythrite or red cobalt is a secondary hydrated cobalt arsenate mineral with the formula (Co 3 (AsO 4) 2 ·8H 2 O). Erythrite and annabergite (Ni 3 (AsO 4) 2 ·8H 2 O) (nickel arsenate) form a complete series with the general formula (Co,Ni) 3 (AsO 4) 2 ·8H 2 O. Erythrite from Morocco.
