Cobalt Tetroxide maualuga le tulaga (Co 73%) ma le Cobalt Oxide (Co 72%)

Kobalt (II) Oxidee foliga mai o ni tioata lanumeamata-olive i le mumu, po'o le pauta efuefu pe uliuli.Kobalt (II) OxideE fa'aaogā lautele i le alamanuia o omea e fai ma mea fa'aopoopo e fai ai ni vali ma enamel lanu moana fa'apea fo'i ma le alamanuia o vaila'au mo le gaosia o masima cobalt(II).
Cobalt(II) Hydroxide po'o Cobaltous Hydroxide 99.9% (fa'avae i u'amea)

Kobalt(II) Hydroxide or Cobaltous Hydroxideo se puna tioata Cobalt e le mafai ona solo i le vai. O se fa'aputuga e le o se mea ola e iai le fua fa'atatauCo(OH)2, e aofia ai divalent cobalt cations Co2+ ma hydroxide anions HO−. O le cobalt hydroxide e foliga mai o le pauta mumu-rosa, e mafai ona solo i totonu o acids ma ammonium salt solutions, e le solo i totonu o le vai ma alkalies.
Cobaltous Chloride (CoCl2∙6H2O i le tulaga faapisinisi) Su'ega Co 24%

Cobaltous Chloride(CoCl2∙6H2O i lona tulaga faapisinisi), o se mea malo piniki e suia i le lanumoana pe a mago, e faʻaaogaina i le sauniuniga o se mea faʻagaoioi ma o se faʻailoga o le susū.
Su'ega o le Hexaamminecobalt(III) chloride [Co(NH3)6]Cl3 99%

O le Hexaamminecobalt(III) Chloride o se mea fa'amaopoopo cobalt e aofia ai se hexaamminecobalt(III) cation e feso'ota'i ma ni anion chloride se tolu e fai ma counterions.
