Strontium thiosulfate Usage And Synthesis
DescriptionStrontium thiosulfate has the molecular formula of SrS2O3 and the molecular weight of 199.7502 g/mol. It can be prepared by the reaction of sodium thiosulfate upon the chloride:
SrCl2+Na2S2O3 SrS2O3+2NaCl
It is moderately soluble in water (12.5 g/100 ml at 15°C) so that the solution must be evaporated at a low temperature to crystallize the product (salt-out temperature ～15°F (-9.4°C). A pentahydrate, SrS2O3·5H2O, is the result.Its density is 2.17 g/cm3 and it loses four waters of hydration at 100°C and decomposes at 225°C. In air, it forms sulfur plus strontium sulfate but the decomposition in an inert atmosphere remains unknown.
It is insoluble in ethanol and acetone. Its solubility in water varies with temperature.
Chemical PropertiesFine needles. Soluble in water; insoluble in alcohol.
