 == The three Is == 

 Hi. I don't know how I ended up here, but the only thing I was interested in finding out isn't mentioned on the page. Could someone add a short paragraph explaining what the three IIIs in iron(III) oxide mean for those initiates such as I?  Thanks.   
 :It is a Roman numeral 3, and it indicates that the oxidation state of the iron here is +3.  If you write it as an ionic structure, that means the iron has a charge of +3.  There is another iron oxide where the iron has a +2 oxidation state, and that is called iron(II) oxide.

 Anyone got any ideas on how to make iron(III) solutions??
