Today, we set out to analyze whether using iron II instead of iron III would produce different results with regards to the formation of the iron-curcumin complex.
At the onset, we hypothesized that the proportion of iron II to curcumin would be 1:2, in contrast to the previous iron III 1:1 ratio.
During our observations, we noted that our UV-Vis spectra showed that absorption at the wavelengths corresponding to our iron-curcumin complex decreased after reflux. This likely means that the formation of the complex is exothermic, that is, adding heat to our solutions pushes the reaction in the reverse direction. Dr. K noted that he had been misled by some of the existing literature, and that we should comb our articles to see from where the faulty conclusion about the utility of refluxing our solution came.
