Chemical formula for cobalt II chloride?

Answer 1

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)

Answer 2

Cobalt (II) has an oxidation number of 2+.

Carbonate (CO3) has an oxidation number of 2-.

Therefore, cobalt (II) carbonate has a formula of CoCO3.

Answer 3

The formula of cobalt II hydrogen carbonate is:

Co(HCO3)3 cobaltic is Co3+ which makes it Co(HCO3)3 not 2

Answer 4

Co(HCO3)2

Because Co (II) has a 2+ charge and HCO3 has a - charge and must be balanced

Answer 5

The chemical formula for cobalt II chloride is CoCl2, which indicates that it contains one cobalt ion with a +2 charge and two chloride ions with a -1 charge each.

Answer 6

Co(HCO3)2

Answer 7

CoCl2
