IRON - chemguide

Iron ions as a catalyst in the reaction between persulphate ions and iodide ions. The reaction between persulphate ions (peroxodisulphate ions), S 2 O 8 2-, and iodide ions in solution can be catalysed using either iron(II) or iron(III) ions.. The overall equation for the reaction is:


The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole.
