190 F. H. Storer on Nitric Acid and Chlorate of 
Art. XXI.—Contributions of the Massachusetts Institute of 
Technology. 1—On Nitric Acid and Chlorate of Potassiwm 
as an Oxydizing Mixture applicable to Sulphur, Sulphids, 
Chromium, Arsenic, Organic Matters, etc., Frank H. 
Storer, Professor of General and Industrial Chemistry in 
the Massachusetts Institute of Technology. 
Some years since while studying the action of various oxyd- 
izing agents upon oxyd of chromium, I was struck by the 
superior oxydizing power of a mixture of ordinary nitric acid 
and chlorate of potassium over that of the mixtures of chlorate 
of pierre and chlorhydric or sulphuric acid, commonly 
used in analysis. Inasmuch as the fact of the great oxydizing 
power of a mixture of nitric acid and the chlorate had already 
ogy with the view of testing the capabilities of the process :—
