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 how much money down for a construction loan https://recyclellite.com
