Elements and Inorganic Compounds

This series, which has been translated from the Russian, consists of five volumes (about 5500 pages) and is a selection from the literature of data on the solubilities of elements, inorganic compounds, and organic compounds in binary, ternary, and multi-component systems. References are given to sources of data in the literature. The data are uncvaluated and refer to temperatures for which experimental data exist. Also see the three volume extension edited by Si 1cock [136].

The two most useful supplementary techniques for the light microscope are EDS and FTIR microscopy. Energy dispersed x-ray systems (EDS) and Eourier-transform infrared absorption (ETIR) are used by chemical microscopists for elemental analyses (EDS) of inorganic compounds and for organic function group analyses (ETIR) of organic compounds. Insofar as they are able to characterize a tiny sample microscopically by PLM, EDS and ETIR ensure rapid and dependable identification when appHed by a trained chemical microscopist. 

The following discussion on health and safety aspects of titanium compounds is concerned only with the behavior of the titanium present in inorganic compounds and not with the effects of the compounds themselves. For example, titanium tetrachloride must be treated with care because of the effects of the hydrochloric acid and heat produced when it reacts with water, not because of the possible toxicity of titanium. Apart from very few exceptions, the inorganic compounds of titanium are generally regarded as having low toxicity. Because of the ubiquitous nature of the element and its compounds, average concentrations of titanium in blood have been determined at 130—160 Fg/L (182—184), with a typical value of 10 Fg/L in urine (185). 

Zone refining can be appHed to the purification of almost every type of substance that can be melted and solidified, eg, elements, organic compounds, and inorganic compounds. Because the soHd—Hquid phase equiHbria are not favorable for all impurities, zone refining often is combined with other techniques to achieve ultrahigh purity. 

Other methods for indicating or implying the presence of an atom in a nonstandard valence state have been used, especially the use of the prefix hydro e.g. 108). Such methods are sometimes convenient for simple molecules, but they are difficult to apply generally. A more general method that has seen extensive use utilizes the italicized symbol for the element with a superscript Roman numeral to indicate the valence (e.g. 109). This method has been objected to, however, because of ambiguity the superscript Roman number is also used to indicate oxidation number in inorganic compounds, and italicized atomic symbols are customarily used as locants for substituents. The A convention is a modification of the principle of this method, and avoids the objection. It was made a Provisional Recommendation of lUPAC in 1981. 

As noted above, an element is a substance that contains only one kind of atom (although it may contain different isotopes of that element). There are 91 elements known to occur in nature, and yet there are many thousands of inorganic compounds, and several millions of organic compounds. Clearly,... 

Very limited experimental data for critical constants and acentric factor are available for inorganic compounds and elements which are solids at room temperature. Thus, the estimates for these substances should be considered rough approximations in the absence of experimental data. 

The present book devotes a lot of space to the synthesis of the most important inorganic compounds and the chemistry of the elements. Since the book contains a large number of experiments and syntheses, they cannot be performed by the students during the time allotted for practical work, and the authors have divided the laboratory works of each chapter into two parts. The first describes the obligatory experiments, and the second, supplementary experiments and syntheses. 

Phosphorus (3IP, 7= 1/2) represents another element sensitive to NMR and consists of only one natural isotope. It has been studied since the beginning of NMR because it is an important element in the composition of inorganic compounds and has a very important role in biology. 

Wilh Ihe exception of hydrogen, carbon forms more compounds than any of the other chemical elements. Traditionally, carbon compounds fall into two fundamental classes (1) inorganic compounds and (2) organic compounds. 

From a data collection with 349 experimental values for the critical compression factor (Reid et al., 1987) obtained with organic and inorganic compounds and elements, a mean value of Zc = 0.2655 is obtained with a standard deviation of a = 0.0346.
