  • Experiments with the Ammonium Amalgam
    Experiments with the Ammonium Amalgam. [from THE AM. JOURNAL OF SCIENCE, VOL. XL, SEPT., 1865.] EXPERIMENTS WITH THE AMMONIUM AMALGAM, BY CHARLES M. WETHERILL, Ph.D., M.D. The existence of the hypothetical radical NH 4 depends less upon the characteristics of its so-called amalgam than! upon the parallelism of its salts with those of the alkalies. If, from these analogies, we accept the metallic nature of ammonium, it will be difficult to avoid assigning a similar character to the rad- icals of all of the organic bases; and especially to those which, like the compound /ammonias, have an alkaline reaction and possess physical and chemical properties so like ammonia. If such be the inference, we must admit numerous compound metals exists only in certain of , which states of combination their elements. The assumption of the elementary nature of a metal is destroyed and the ideas of the alchemists are re- ; a may vived for if NH 4 be metal and NH 3 be not one, why not other metals, esteemed elements, be also compounds. In examining the so-called ammonium amalgam one is inter- ested at the great resemblance which it bears to the amalgams proper in its physical properties. The mercury has lost its flu- idity or mobility, and, at the same time, its relations of cohesion and adhesion are very sensibly altered. It no longer coheres powerfully; but adheres to, or Wets, platinum, iron and other metals, like the potassium or sodium amalgam. When left to C. M.

MIF is a powerful tool in understanding the Hg transformations and reaction mechanisms. Here we look into the MIF of the two odd isotopes of mercury (199Hg and 201Hg) in sediment samples collected from lakes and springs of Florida, Lake Erie, and Yucatan Peninsula. The '199Hg and '201Hg of the sediments range from + 0.52‰ to -0.48‰. From the isotopic signature we interpret the possible source of Hg in the Yucatan Peninsula carbonate to be Hg(II) from the water column. Hg in the Florida lakes and spring sediments primarily comes from litterfall. Lake Erie appears to have an anthropogenic source. This study suggests that the MIF signature of Hg isotopes can be used to qualitatively determine the primary source(s) of Hg in sediments. © 2015 The Authors. Published by Elsevier B.V.

  • Understanding the 2016 Gubernatorial Elections by Jennifer M
    GOVERNORS The National Mood and the Seats in Play: Understanding the 2016 Gubernatorial Elections By Jennifer M. Jensen and Thad Beyle With a national anti-establishment mood and 12 gubernatorial elections—eight in states with a Democrat as sitting governor—the Republicans were optimistic that they would strengthen their hand as they headed into the November elections. Republicans already held 31 governor- ships to the Democrats’ 18—Alaska Gov. Bill Walker is an Independent—and with about half the gubernatorial elections considered competitive, Republicans had the potential to increase their control to 36 governors’ mansions. For their part, Democrats had a realistic chance to convert only a couple of Republican governorships to their party. Given the party’s win-loss potential, Republicans were optimistic, in a good position. The Safe Races North Dakota Races in Delaware, North Dakota, Oregon, Utah Republican incumbent Jack Dalrymple announced and Washington were widely considered safe for he would not run for another term as governor, the incumbent party. opening the seat up for a competitive Republican primary.

  • 1 Submission from the EU on Mercury-Added Products And
    Submission from the EU on mercury-added products and manufacturing processes using mercury or mercury compounds In accordance with Decision MC-3/16: Review of Annexes A and B, the Secretariat called in a letter dated 13 December (MC/COP3/2019/15) for submissions from Parties by 31 March 2020, including: a) Information on mercury-added products and on the availability, technical and economic feasibility, and environmental and health risks and benefits of non-mercury alternatives to mercury-added products, pursuant to paragraph 4 of article 4 of the Convention b) Information on processes that use mercury or mercury compounds and on the availability, technical and economic feasibility and environmental and health risks and benefits of mercury-free alternatives to manufacturing processes in which mercury or mercury compounds are used, pursuant to paragraph 4 of article 5 of the Convention The EU would like to share the information on a number of products and processes listed in table 1 below, where EU law is stricter than the provisions of the Convention. Each product/process is covered in an individual fiche, including data sources and references. The submission also includes a fiche on re-emerging use of mercury used as propellant in ion engines. New information has surfaced regarding this specific use which is likely to cause a significant dispersion of mercury to the environment. Note that the EU submission is based on the European Commission study on the "Collection of information on mercury-added products and their alternatives". The final report has a wider scope than the EU submission as it also covers a number of other existing or emerging uses and has been published and made available on CIRCABC.

  • Been Regarded As a Distinguishing Characteristic of Electrolytic Con
    634 CHEMISTRY: LEWIS AND HWIVE ELECTRICAL CONDUCTION IN DILUTE AMALGAMS By Gilbert N. Lewis and Thomas B. Hine DEPARTMENT OF CHEMISTRY, UNIVERSITY OF CALIFORNIA Reeived by the Academy. October 17.1916 The modem theory of electrical conduction in metals, according to which the metal is dissociated to give a positive ion of low mobility, which is characteristic of the metal, and a negative carrier of high mo- bility, which is common to all metals and presumably to be identified with the electron, has given rise to certain misgivings, despite the com- plete analogy between this theory and the accepted theory of electro- lytic dissociation. It is true that in the case of solid metals the crystal- line forces, which lead to the formation of the various components of the metal into symmetrical space-lattices, produce conditions which have no counterpart in liquid electrolytes, but in the case of a liquid metal like mercury we must assume that it differs from any electrolyte -we are tempted to say from any other electrolyte-only in as far as one of its ions has properties which differ very greatly in degree, but probably not in kind, from the properties of other ions. If therefore we should ultimately find that the Arrhenius theory of ionization is not applicable to a liquid metal we should be inclined to believe that it is not completely valid in the case of electrolytes. This theory of electrolytic dissociation, which was originally pro- posed to explain the properties of aqueous salt solutions, has since been successfully applied without essential modification to many types of non-aqueous solution.
