  1. aThiosulfate standards have pH > 7. In the field KCN was added to the samples to convert polythionates to SCN- using cyanolysis.74 Hence, this test pertains to the stability of SCN- over time as a measure of polythionate concentration and the formation of additional polythionate over time, which would be converted to SCN- in the bottle.
