Abstract

Abstract The end point in the titration of sulfate with barium chloride using tetrahydroxyquinone as a color indicator has been rendered more reproducible by use of a filter photometer with a recorded output. It has been possible to determine organic sulfur in 5–7 mg samples oxidized in a Schoniger flask in 15 minutes of working time, with an average sulfur recovery for 24 determinations on four widely different types of compounds of 99.98%, with a standard deviation of 0.35, and average recoveries of sulfur for each of the four compounds ranging from 99.92 to 100.11%. Nitrogen does not interfere.
