How to measure concentration of Fe2+ and Fe3+
« on: August 17, 2009, 07:24:20 AM »
Anyone know how to measure the concentration of Fe2+ and Fe3+ in a solution containing mix Fe2+ and Fe3+?
Let say in a mix FeSO4 and Fe2(SO4)3 ?

thank you so much

ORP electrode for ratio, reduction plus titration for sum of both (http://www.titrations.info/permanganate-titration-iron for example).
