Abstract

At the present time, the test for sulfide is often made by placing a portion of the sample in an acid solution and identifying the gas evolved either by its odor or by holding a piece of moistened lead acetate paper in the evolved gas. The test for carbonate is often made in a similar war, except for the fact that a drop of barium hydroxide solution is used to identify the gas that is evolved. Both of these tests become increasingly uncertain as the size of the sample being tested is made smaller and smaller, which is the case in semimicro qualitative analysis. This paper describes a test that will detect 0.0001 g. or less, of sulfide ion in 1 ml. of solution, and also a test that will detect 0.001 g. or less, of carbonate ion in 1 ml. of solution.
