PmiTER MILLER When a potassium salt is added to a solution of phosphotungstic acid a characteristic dense, white, difficultly filterable precipitate is formed. The test is as sensitive as any of the tests commonly used; one cc. of a ten percent solution will give an easily distin-guishable precipitate with Ice. of 0.02 M potassium chloride. Ammonium, which also forms a very insoluble compound, inter-feres, and must first be removed.
