Some approximate values of the concentrations of the chlorine ion and the mean activity coefficients of HCl in Dowex 50, as functions of the mean activity of HCl are given. The KCl uptake by anion-exchange resins, Dowex 1 and 2, is plotted. Ion-exchange phase properties of HCl were determined from freezing point measurements. The thermodynamic acid dissociation constants of HClO/sub 4/, HCl, HNO/sub 3/, HBr, and HGaCl/sub 4/ in water-saturated bis(2- chloroethyl) ether, were obtained from couductometric measurements. The distribution behavior of InBr/sub 3/ and IuCl/sub 3/ in HBr and HCl was studied. Information is given on the extraction of Zn and Ag from chloride solutions by dioctylamine salts. Ion exchange equilibria between hexammino-cobalt(III) and chloro-pentammino-cobalt(In ions in respect to La ions in Dowex 50 NaR are plotted. Typical radiochemical activation analyses for K in geologic materials are tabulated. The postulated nuclear level scheme and the calculiated and experimental positron decay following ( gamma , n) activation of Br/sup 79/ are shown for Br/sup 78/. Cumulative fission yields in the deuteron fission of U/sup 235/ are tabulated. Cosmic ray data obtained with a new highcounting rate meson monitor are plotted. The equipment used and data obtained in a search for long- lived particles with mass ~ 550m/sub e/ in the cosmic-ray flux at sea level are shown. The excited states of Ni/sup 58/ and Ni/sup 61/ obtained from (d, p) reactions of Ni/sup 58/ and Ni/sup 60/ are tabulated. (For preceding period see AECU-3685.) (M.H.R.)

The International Union of Pure and Applied Chemistry (IUPAC) Inorganic Chemistry Division has published a Provisional Recommendation for the names and symbols of the recently discovered superheavy elements 113, 115, 117, and 118. Tennessine (Ts) is proposed for element 117, recognizing the contribution of Tennessee research centers ORNL, Vanderbilt and the University of Tennessee to superheavy element research.

The International Union for Pure and Applied Chemistry has announced formal verification of four new chemical elements, recognizing the Department of Energy’s Oak Ridge National Laboratory and its collaborators for the discovery of elements 115 and 117.

This third edition has resulted from a major review of the content of most of the tables, the introduction of a few new tables that were suggested by users, and a decision to introduce hazard codes for inorganic and organic compounds. The text emphasizes the relationship between the structure and chemical properties, and the physical properties of the compound they make up. It includes risk and safety codes which provide details of associated hazards. The integration of data and risk and safety codes offers a personal reference source for material which is otherwise not readily available to students. The recommended methods of handling hazardous chemicals are clearly defined, making the book ideal as a laboratory manual.
