Some iron(III) salts, like the chloride FeCl3, sulfate Fe2(SO4)3, and nitrate Fe(NO3)3 are soluble in water. However, other compounds like oxide Fe2O3 (hematite) and iron(III) oxide-hydroxide FeO(OH) are extremely insoluble, at least at neutral pH, due to their polymeric structure. Therefore, those soluble iron(III) salts tend to hydrolyze when dissolved in pure water, producing iron(III) hydroxide Fe(OH)3 that immediately converts to polymeric oxide-hydroxide via the process called WebSep 13, 1991 · The iron phosphate treatment procedure, e.g. for steel, galvanised or zinc plated iron or aluminium prior to applying powdered or liq. paint or an organic coating, consists of regulating the pH value in the successive treatment stages from a de-greasing stage in an alkaine medium at pH between 9 and 13 through a rinsing stage to a …
