CoCl3 is the chemical formula.
Common oxidation states of cobalt include +2 and +3, so possible chlorides are: CoCl2 and CoCl3 , but the last one is rare.
(CoF3 (Co(III)-fluoride) is a better possibillity to prove this oxidation state)
Maximum oxidation state is +5, though Cobalt can easily 'coordinate' with in total 6 coordinative groups (=CG) and negative ions: Co(CG)4Cl2 (a coordinative group migh be a < -N| >-atom group of ammonia, ethylenediamine or haemoglobin)
if there's that dot in the between the chloride and the water molecule: cobalt (II) chloride hexahydrate.Cobalt(II) Chloride Hexahydrate
Co(II)F3 The three needs to be small
The chemical Formula for Cobalt II hydrogen carbonate can be given.It is as follows :Co2HCO3.
The chemical formula for cobalt II acetate is Co(C2H3O2)2.
The formula for cobalt(II) chloride hydrate is CoCl2·xH2O, where x represents the number of water molecules attached to each cobalt(II) chloride molecule.

CoCl2 cobaltous chloride or cobalt(II) chloride
CoClO3 is the chemical formula for cobalt(II) chlorate. It is a compound formed by the cobalt(II) cation (Co2+) and the chlorate anion (ClO3-).
The chemical formula for cobalt(II) bromide is CoBr2.
The chemical Formula for Cobalt II hydrogen carbonate can be given.It is as follows :Co2HCO3.
The chemical formula for cobalt II acetate is Co(C2H3O2)2.
The formula for cobalt(II) chloride hydrate is CoCl2·xH2O, where x represents the number of water molecules attached to each cobalt(II) chloride molecule.
The chemical formula for nickel(II) chloride is NiCl2.
Cobalt II has a +2 charge and is written Co2+. Nitrite has a -1 charge and is written NO2-. Therefore, you must have two nitrite anions for every Cobalt II. It is written... Co(NO2)2
The chemical formula for cobalt(II) sulfide is CoS. It consists of one cobalt atom and one sulfur atom.
The chemical formula for mercuric chloride is HgCl2.
