Book Description
Excerpt from The Journal of the American Chemical Society, 1899, Vol. 21 In the investigations of Walker and Aston and also in those of Long the polariscope was used exclusively to follow the prog ress of the inversion. This is no doubt the simplest and most accurate method to use whenever it is applicable. It is evident, however, that the polariscope cannot be used in working with colored solutions and that the accuracy of measurement with this instrument is greatly impaired when the solutions are not perfectly clear. Long cites several instances where, after pro longed heating, the solutions became somewhat colored or turbid, making their polarization difficult. The objects of this investigation are (1) to find a method by means of which the speed of inversion of sugar by colored salts can be determined, and (2) to compare the basicity of the met als as ascertained by the method of sugar inversion with their so-called solution tensions, as found by the measurement of the electromotive forces of galvanic chains.

Book Description
Excerpt from The Journal of the American Chemical Society, 1899, Vol. 21: Part II The essential part of the apparatus is the water-cooled stopper for closing the crucible. The construction of this stopper will be readily understood from the sketch. The stopper is made of sheet copper, the joints being brazed. It is, of course, essential that it should be as near perfectly circular as possible, with no indentations or imperfections in the brazing. The sides of the stopper should not are more than the sides of the crucible at the top. Too much are has a tendency to cause the stopper to be forced out of the crucible when under pressure.

Book Description
Excerpt from Journal of the American Chemical Society, 1881, Vol. 3 At that time, and even now, the generation of ammonium nitrite by evaporation of water was, and is taught, as an established fact. If this were indeed the case, the ozonising chambers present the most favorable conditions for its generation, and the nitrite thus formed would give the same reaction as hydrogen peroxide or ozone, when we came to titrate the water in the ozonisers with an acidified solu tion of potassium iodide. The elaborate experiments of Bohlig, Zabelin and Carius, however, have Shown that this is not true, and that the alleged formation of ammonium nitrite by evaporation of water in air, never takes place when adequate precautions are taken to exclude from the evaporated water, the ammoniacal compounds pre-existent in the atmosphere. Fortunately, therefore, this source of error was not inherent in the experiments themselves, and it only remained to guard against it by very complete washing of the air drawn through the ozonator.

Excerpt from The Journal of the American Chemical Society, 1901, Vol. 23 A separate investigation, in the method suggested by Renard, ' was conducted to determine the presence of arachidic acid. A small crop of crystals was obtained, showing the characteristic form of arachidic acid under the microscope, but the quantity recovered was too small for further investigation.
