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 WebIn print, we use roman numerals in parentheses to represent the charge on the ion, so these two iron ions would be represented as the iron(II) cation and the iron(III) cation, … WebFerric ions are amongst the most essential metal ions in biological systems and its deficiency as well as excess accumulation lead to several diseases including anaemia and even cancer [51,52].
