Page 86. Binoxide of Nitrogen and Hypo-nitrous Acid.—Binoxide of nitrogen is formed when nitric acid and a little water are added to some copper turnings. It produces deep red fumes as soon as it comes in contact with the air, by combining with the oxygen of the latter to form hypo-nitrous acid. Binoxide of nitrogen is composed of two parts oxygen and one part of nitrogen; hypo-nitrous acid is composed of one part of nitrogen and three parts of oxygen.
