The compound sodium thiosulfate pentahydrate, Na2S2O3 • 5H2O is important commercially to the photography business as
“hypo,” because it has the ability to dissolve unreacted silver salts from photographic film during development. Sodium thio-
sulfate pentahydrate can be produced by boiling elemental sulfur
in an aqueous solution of sodium sulfite.
Sg(s) + Na2SO3(aq) + H2O(l) → Na2S2O3.5H2O(s)
(unbalanced) What is the theoretical yield of sodium thiosulfate pentahydrate when 3.25 g of sulfur is boiled with 13.1 g of sodium sulfite? Sodium thiosulfate pentahydrate is a very soluble in water. What is the percent yield of the synthesis if a student doing this experiment is able to isolate (collect) only 5.26 g of the product
