The inorganic sulfate content of several typical anionic surface active agents has been determined by a potentiometric titration with lead nitrate using the potassium ferri‐ferro cyanide couple to detect the end point. The recovery of added sodium sulfate varied from ‐6 to +5% of the contained amount at the 0.5% sulfate level.
