Dissolve 19 g of Na2S2O3 (or enough Na2S2O3.5H2O to give 19 g of Na2S2O3) in 1 liter of distilled water. Add about 0.1 g of Na2CO3 to keep the solution neutral or slightly alkaline and thereby retard decomposition to elemental sulfur. If you wish, you may prepare this solution quantitatively as a check on the normalities (molarities).
