Abstract
Sulfate was indirectly determined by precipitating sulfate as BaSO/sub 4/ and then dissolving BaSO/sub 4/ in excess ammoniacal EDTA. The excess EDTA was titrated potentiometrically with La/sup 3 +/. A cupric-selective electrode was used to detect the end point. About 10/sup -3/M SO/sub 4//sup 2 -/ was determined in 3M HCl solutions of metal oxides with a relative standard deviation of 3.5 percent and a bias of +4 percent.
