Iron hydroxide to iron oxide
WebThe iron (III) ions react with hydroxide ions to produce hydrated iron (III) oxides (also known as iron (III) hydroxides): Fe3+(aq) + 3OH-(aq) → Fe (OH)3(s) The loose porous rust or Fe (OH) 3 can slowly transform into a … WebMar 29, 2024 · This reaction can be written in words as iron III combining with oxygen gas to form iron III oxide. You know it is iron III, not iron II, because oxygen is always #O^(2-)#, so the only way that #Fe_2O_3(s)# is neutral is if the iron has a charge of #3+#. Answer link. Related questions.
