Iron(Ⅲ)hydroxide - Nature
Open Data Verified Data
dark brown flocculent precipitation, the relative density of 3.4~3.9, heating gradually decomposed into iron oxide. It is amphoteric, but its alkalinity is stronger than acidity. The newly prepared ferric hydroxide is soluble in inorganic acid and organic acid, and can also be dissolved in hot concentrated alkali. The solubility in the acid varies with the length of time the article is made and is difficult to dissolve after several times. Insoluble in water and ethanol. Strong oxidants, such as sodium hypochlorite, in alkaline medium, the new system of iron hydroxide oxidation into VI oxidation of sodium ferrate Na2 Fe04. The hydrous iron oxide III of colloidal precipitation has strong adsorption properties.
