Journal of Wood Chemistry and Technology 1982 , 2 (2) , 115-127. Cobalt(III) hydroxide or cobaltic hydroxide is a chemical compound with formula Co(OH)3 or H3CoO3. The brownish-black form is a stable solid and can be prepared by reaction of water solutions of cobalt(II) chloride and sodium hydroxide, followed by oxidation with ozone. Cobalthydroxide. Question: Is Co(OH)2 ( Cobalt(II) hydroxide ) Soluble or Insoluble in water ? The Effect of Cobalt on the Degradation of Methyl β-D-Gluco-Pyranoside by Oxygen in Aqueous Sodium Hydroxide Solution. Example: The solubility of silver sulfate, Ag2SO4, is 0.025 M at 25oC. Cobalt(II) hydroxide, 95%, pure. The resulting dark green powder is fairly stable at liquid nitrogen temperature, but at room temperature it turns dark brown within a few days. - Kiev: Naukova dumka, 1972.
