Recommended Reference Materials for Realization of Physicochemical Properties deals with recommended reference materials for realization of physicochemical properties, including water, mercury, 2,2,4-trimethylpentane, cyclohexane, and trans-bicyclo[4,4,0]decane for density measurement. Nomenclature and units are given, and the methods of measurement are described. This book first presents the nomenclature and units used in the determination of densities of liquids and solids, followed by a general description of the apparatus and the methods used in the measurement of density, with particular reference to the pycnometric, hydrostatic weighing, magnetic float, and temperature flotation methods. The use of water as a density reference material is then explained, focusing on the isotopic composition of Standard Mean Ocean Water (SMOW) and the absolute density of SMOW as a function of temperature. Problems due to the effect of pressure and dissolved gases on the density of water are also considered. Finally, the use of mercury, 2,2,4-trimethylpentane, cyclohexane, and trans-bicyclo[4,4,0]decane as reference materials in density measurement is discussed. This monograph will be a useful resource for physical chemists and chemistry students.
