WebHowever, unless it is very pure and freshly prepared, iron(II) will probably give a faint red colour due to the presence of some iron(III). Iron(III) oxidises iodide ions to iodine which gives the characteristic blue-black colour with starch. Iron(II) should give no reaction unless it contains some iron(III). 2Fe 3+ (aq) + 2I – (aq) → I2(aq ... WebThe iron reacts with water and oxygen to form hydrated iron (III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron (III)...
