WebThe iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. WebAll acid-base titrations that are measured by a pH probe are potentiometric; thus, this method is not as unusual as it may seem. You will conduct an oxidation-reduction reaction in this experiment in order to determine the amount of iron (II) ions in a solid sample of ferrous ammonium sulfate hexahydrate, (NH 4) 2 Fe (SO 4) 2 •6H 2 O. natuzzi brown leather sectioanal recliners
