when, if the acids in question are present, their odor will be apparent.* 11 203. NITRITE OF AMYL. C,H,,NO,. A light-yellowish liquid, darkening when heated, of spec. grav. 0.877, boiling at about 96° C. Its vapor has a reddish-yellow color. Its odor resembles that of ethyl nitrite.-Sulphuric acid (concentrated) decomposes it with explosive violence, sometimes with combustion. Alcoholic potassa decomposes it quickly, forming potassic nitrite aqueous potassa decomposes it slowly. * Farther, see Prescott's Examination of Alcoholic Liquors, New York, 1875.
