Page 401 - ... of the nickel-carbonyl thus diluted consists of two parts : (1) the spectrum of the main body of the green flame, (2) that of the base of the flame when the oxygen is outside, and of the surface of the small inner cone when the oxygen is inside, the flame. The spectrum of the main body of the...
Page 437 - ... sp. gr.), heat applied gently, then 160 cc of a mixture of equal parts of nitric acid and water added, care being taken to keep down the temperature. In this way a solution of known strength is got, and little difficulty will be experienced in using the requisite quantity, namely, 40 parts of molybdic acid for every i part of phosphoric acid present.
Page 414 - C or the concentration of the nitrons acid are concordant with those calculated according to the above diffeiential equation within the limits of experimental error. The rate is dependent upon the ratio of the masses of the nitrous and nitric acid, being the more rapid, the greater the proportion of the former to that of the latter. In the particular case of the liquid prepared from nitric oxide and nitric acid, wherein the reproduction of solutions of similar concentration presents less difficulty,...
Page 149 - Mag. [4] xiv, p. 418 (1857) in the same way as in the free state, but modified to a greater or smaller extent by the metal with which it is combined. The following is a summary of the results arrived at : — (1) The absorption spectra of the three salts examined undergo changes on diluting their solutions. (2) These changes are of such a nature that the spectra tend to become identical in dilute solutions. (3) The results of other observers show on the whole that salts of other metals behave in...
Page 16 - ... increased, as the temperature is raised, and as the duration of action is extended. It appears further, at least when the acid is not present in proportion greater than 50 per cent of the [1 : 1] mixture, that in the early stages of the action the oxygen lost to the permanganate is liberated, and that later on the decomposition of the permanganate results in the precipitation of manganese in the form of a higher oxide or in the retention of the manganese in solution in the form of a higher sulphate....
Page 16 - ... in the course of five days. It is evident also that twenty per cent of the [1 : 1] acid produces no appreciable effect at ordinary temperatures and under exposures of a few hours only. The effect of heating the mixture of acid and permanganate to 80° C. for an hour and a half is closely comparable with that brought about by the five days action at the ordinary temperature.
Page 42 - Varren trap nitrogen bulb, the exit tube of which is drawn out, so that it may be pushed well within the inlet tube of a Will and Varrentrap absorption flask. A third receiver simply acts as a trap to exclude air from the absorption apparatus proper. The titration should be completed immediately after the distillation, during which the nitrogen bulbs should be immersed in cold water; otherwise, traces of dissolved nitric oxide might get oxidized and liberate more iodine. Another method worked out...
Page 47 - In case the total chlorides exceed 0.2 gram it may be advisable to decant the liquid, wash the residue, redissolve, and repeat the precipitation. If this be not done, the precipitate should be redissolved with the least possible quantity of water, a few drops of hydrochloric acid...
Page 63 - Generalizations. 1. Corresponding Temperatures and Pressures. — It must, I think, be concluded that the statement that " if the absolute temperatures of various substances are proportional to their absolute critical temperatures their vapour-pressures will be proportional to their critical pressures " has not been proved by experiment to be true except in a very limited number of cases; indeed, when the alcohols and acetic acid are compared with fluorbenzene, the statement is quite wide of the...
Page 507 - F. Guthrie (Phil. Mag. [4] xv. 64). An aspirator which works by a constant stream of water and does not require any filling or emptying of vessels, has been contrived by MW Johnson (Chem. Soc. Qu. J. iv. 186). The principle of this apparatus is the same as that of the waterblast used in the Hungarian mines. The apparatus...
