Ferric oxalate synthesis
The discovery of the efficient photolysis of the ferrioxalate anion was a landmark for chemical photochemistry and actinometry. The potassium salt was found to be over 1000 times more sensitive than uranyl oxalate, the compound previously used for these purposes. The synthesis and thermal decomposition of potassium ferrioxalate is a popular exercise for high school, college or undergraduate university students, since it involves the chemistry of transitio… WebThe equation for the formation of ferrous oxalate is: Fe (NH4)2(SO4)2. 6H2O (aq) + H2C2O4(aq) FeC2O4. 2H2O (s) + 2 (NH4)HSO4(aq) + 4H2O Before the concentration of iron in the sample can be determined, the iron in the product is transformed into a new complex using the phenanthroline molecule.
