The coordination number and dissociation constant measurement of complex consisting of Iron(Ⅲ) and 4, 5-Dihydroxy-1, 3-benzenedisulfonic acid disodium salt (Tiron) has been widely employed as a teaching experiment in university. However, with varying of the ratio of iron(Ⅲ) and Tiron a distinct absorption peak shifts have been observed, indicating the non-unique complex in solution. Non-negative matrix factorization was applied to analyses the spectra data, and the characteristic spectrum and coordination number of each component were obtained. The results showed the coexistence of mono-and bis-tiron complexes of Iron(Ⅲ) in the solution, and this does challenge the rationality of this system as a teaching experiment because the coordination number should be positive integer according to the text book.
