<p>Aluminium tridecamer (Al13) has seemed to be stable in solutions because of its Keggin structure. Recently, some studies suggested that Al13 would be decomposed under specific conditions, especially under the sulfate ion’s existence. However, the fact is that the reason that the sulfate ion leads Al13 to be decomposed has not been clearly revealed yet. The main aim in this study was to evaluate the effect of the sulfate ion on Al13 with Electrospray Ionization Mass Spectrometry (ESI-MS). The sulfate ion, which is an oxidant, was added to Al solutions before and after Al13 formed. To discuss the results, the same experiments were carried out with ascorbic acid, which is a reductant, instead of the sulfate ion. As results of these experiments, it was deniable that a small amount of oxidation could deprive the Keggin structure of electrons, and thus caused the decomposition of Al13. On the contrary, a much greater amount of ascorbic acid than that of sulfate ion would cause the decomposition of Al13 by giving electrons into the Keggin structure. From these results, the Al Keggin structure maintains its itself even under the existence of a reductant.</p>
