Excerpt: ...gas will be found to be one-third the volume of the chlorine originally in the tube. The tube may be previously roughly graduated in thirds by rubber rings, allowance being made for the space occupied by the cork. A simpler method is to measure the distance from the base of the cork to the stop-cock in centimeters. The residual gas will measure one-third of this distance when the bulb is held in an upright position. By removing the cork the gas may be tested and shown to be nitrogen by extinguishing a splinter. A glass tube, 1 m. long and 15 to 20 mm. in diameter, sealed at one end and fitted with a one-holed rubber stopper through which the stem of a small dropping-funnel passes, may be used in case the eudiometer is not at hand. The tube is filled with chlorine, as above, inverted with the thumb over the mouth of the tube, and the cork on the stem of the dropping-funnel quickly thrust into the open end of the tube. The stem of the dropping-funnel should have been previously filled with strongest ammonium hydroxide. The funnel is then filled with the hydroxide, and a few cubic centimeters allowed to fall drop by drop into the gas. As each drop falls, it is seen to emit a feeble flash of light, a phenomenon not observable when the other form of eudiometer is used. The remaining operations are identical with those described above. 2 NH3 3 Cl, = 6 HCl N2. NH3 HCl = NH4Cl. Eudiometer (Fig. 11, p. 26); Cl generator; glass tube sealed at one end, 1 m. long, 15-20 mm. diameter; dropping-funnel; rubber stoppers; strongest NH4OH. 36. Decomposition of gaseous ammonia by sodium hypo-bromite and the volumetric relation of the nitrogen liberated.--The volumetric relation of the nitrogen liberated from a given volume of ammonia by the action of sodium...
