Book excerpt: Excerpt from A Revision of the Atomic Weights of Sodium and Chlorine The investigation of the atomic weights of the extremely common elements sodium and chlorine was undertaken because of an unac countable discrepancy which appeared in the composition of a sample of very pure sodic bromide, as compared with the results of Stas. This sodic bromide had been prepared for the purpose of determining the transition temperature of its hydrated crystals and a preparation which yielded a constant transition point, therefore giving evidence of great purity, nevertheless possessed a perceptibly lower combining weight than that indicated by Stas's results. Such a discrepancy as this was not to be passed over lightly. It indicated either an unknown constant impurity in our sodic bromide - and hence a possible error in our transition temperature - or else a flaw in the classical work of Stas. When the first cause of disagree ment had been carefully sought in vain, the second was pursued. Thus a physico-chemical investigation demanding great purity of materials led to a quantitative research of unexpected magnitude and in turn this quantitative investigation depended continually upon physico-chemical methods and considerations. In confirmation of previous work at Harvard, it was found that the physico-chemical conditions of experiment were of as serious import as the purity of the materials, and of far greater significance than an increase in the scale of operations. The essential circumstances here defined must receive consideration in any other research of a similar kind.

This book was released on 2017-10-15 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Further Researches Concerning Atomic Weights of Potassium, Silver, Chlorine, Bromine, Nitrogen, and SulphurThe atomic weight of potassium is a chemical constant of unusual inter est and significance. Standing, as it does, in the middle of the series of five atomic weights of the most electro-positive metals substances which exhibit in a highly marked degree both similarity and progressive change in properties this number must be Of unusual importance in the search for that undiscovered mathematical relationship which undoubtedly exists between these constants. Moreover, the atomic weight of potassium is essentially bound up with the atomic weights of oxygen, chlorine, and silver, this group forming a fundamental basis in the calculation of nearly all the other atomic weights; so that a change in the atomic weight of potassium has a widely ramified effect on the whole table of atomic weights. If any further evidence of this fact were needed, the recent paper of R. W. Gray1 would furnish it.The recent investigation upon the atomic weight of sodium by one of us in conjunction with Dr. R. C. Wells2 showed conclusively that Stas's work, upon which rested earlier knowledge, was somewhat at fault in several respects. The most serious of these errors were, first, the existence of impurity in Stas's silver; secondly, the fact that in his work solid salt was dropped into the argentic solution, causing occlusion of salt; and thirdlv inadequate knowledge concerning solutions of argentic chloride. In View Of these errors it seemed not impossible that a similar revision of potassium might likewise yield slightly lower results for potassium than had been found by this master of exact analysis. For this reason the present investigation was undertaken.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Determinations of Atomic Weights: Further Investigation Concerning the Atomic Weights of Silver, Lithium and Chlorine; The Harvard Determinations of Atomic Weights, Between 1870 and 1910; Methods Used in Precise Chemical Investigation Without attempting to give a complete historical discussion, the most important results of other investigations may be mentioned. The inter esting and valuable results of Dixon and Edgar, l of W. A. Noyes and H. C. P. Weber,2 and of Edgar alone3 upon the quantitative synthesis Of hydrochloric acid furnish less direct evidence upon the matter in hand, for they need the introduction of two other ratios, namely, that of hydrogen to oxygen and that of chlorine to silver, in order to solve the problem.

This book was released on 2017-10-17 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Recalculation of the Atomic Weights Suppose now that for every element we had a goodly number Of atomic weight ratios, connecting it with at least a dozen other elements, and all measured with reasonable accuracy. These hundreds Of ratios could then be treated as equations of Observation, reduced to linear form, and combined by the general method of least squares into normal equations. All errors would thus be distributed, never becoming cumulative; and the normal equations, solved once for all, would give the atomic weights Of all the elements simultaneously. The process would be laborious but the result would be the closest possible approach to accuracy. The data as yet are inadequate, although some small groups Of ratios may be handled in that way; but in time the method is sure to be applied, and indeed to be the only general method applicable. Even if every ratio was subject to some small constant error, this, balanced against the similar errors Of other ratios, would become accidental or unsystematic with reference to the entire mass Of material, and would practically vanish from the final means. Concerning this subject Of constant and accidental errors, a word may be said here. My Own method Of discussion eliminates the latter, which are removable by ordinary averaging; but the constant errors, vicious and untractable, remain, at least partially. Still, where many ratios are considered, even the systematic errors may in part compensate each other, and do less harm than might be expected. They have, moreover, a peculiarity which deserves some attention. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from A Diffusion of Gases and the Density of Chlorine: A Search for Probable Isotopes of Chlorine In the light of all these considerations it seemed probable that ord nary chlorine must be a mixture of isotopes of different atomic weight and that it Should be separable into its constituent parts by diffusion. Such an investigation should be the more valuable since the atomic weight of chlorine is so fundamentally important, especially as the basis of other atomic weight determinations.
