Molecular Nature

Hydrophilic sulfur sols prepared by reaction of aqueous sulfide and sulfite at low pH have been studied by chemical analysis, ion-pair chromatography, and reversed-phase HPLC. The approximate composition of the sol is x(NaHSO4/Na2SO4) ·ySn · zNa2SmO6 with n = 6-10 and m = 4-16. The elemental sulfur Sn accounts for 17% and the polythionate sulfur for 10% of the dry weight (sulfate: 18%). On aging of the sol at 20°C the long-chain polythionates decompose to elemental sulfur and tetrathionate as well as pentathionate. The higher chemical reactivity of this sol compared to S8 is explained by the fact that 45% of the zero oxidation state sulfur (S°) are present as non-S8 molecules.
