| dc.description.abstract | <p>The kinetic instability of iron(III) thiocyanate complexes in aqueous solution, evidenced by the loss of solution colour with time, has made it difficult to determine reliable equilibrium data. A technique, which measures the absorbance of these solutions as a function of time within milliseconds of mixing Fe<sup>3+</sup> with SCN<sup>-</sup> and which extrapolates to an initial spectrum at time zero, has been designed to overcome these difficulties and is described in this paper. Two complexes, Fe(SCN)<sup>2+</sup> and Fe(SCN)<sub>2</sub><sup>+</sup>, have been identified upon analysing the absorbance data for thiocyanate concentrations up to 0.25 M at 25<sup>o</sup>C and an ionic strength of 0.5 M. Equilibrium constants, <em>K<sub>1</sub> = </em> and <em>K<sub>2</sub></em> = have been determined and comparisons made with the literature.</p> | |
