The standard redox potentials of inorganic oxidants used in organic synthesis are generally around or above + 1.0 V. Organic substrates do not have such high potentials. The values for the CH4/CH3OH and CjHj/CjHjOH couples are at +0,59 V and 0.52 V, respectively. The oxidation of alcohols and aldehydes corresponds to values around 0.0 V (W.M. 

The values given in the following table for the heats and free energies of formation of inorganic compounds are derived from a) Bichowsky and Rossini, Thermochemistry of the Chemical Substances, Reinhold, New York, 1936 (h) Latimer, Oxidation States of the Elements and Their Potentials in Aqueous Solution, Prentice-Hall, New York, 1938 (c) the tables of the American Petroleum Institute Research Project 44 at the National Bureau of Standards and (d) the tables of Selected Values of Chemical Thermodynamic Properties of the National Bureau of Standards. The reader is referred to the preceding books and tables for additional details as to methods of calculation, standard states, and so on. 

The nature of ions in solution is described in some detail and enthalpies and entropies of hydration of many ions are defined and recalculated from the best data available. These values are used to provide an understanding of the periodicities of standard reduction potentials. Standard reduction potential data for all of the elements, group-bygroup, covering the s-and p-, d- and/- blocks of the Periodic Table is also included. Major sections are devoted to the acid/base behaviour and the solubilities of inorganic compounds in water. 

This reference work, prepared under the auspices of the lUPAC, contains selected values of electrochemical potentials relative to the assigned zero value of the standard hydrogen electrode at or near 25 C. Entries are given for about 350 Inorganic systems. The literature coverage Is through 1967. 

The results for each of the six plants are presented in this section of the paper and are identified by project plants 1-8. This section addresses those results relevant to occupational exposures (i.e. at or above the Action Level), environmental emissions (i.e. potential air emissions above background) and process equipment (i.e. locations with potential mercury accumulation). Occupational exposures were compared to the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV) for inorganic mercury, 25 pg/scm (micrograms per standard cubic meter). The project sponsor adopted Action Level (AL) is 12.5 pg/scm. The AL is used as an early indicator for potential mercury exposure approaching the TLV.
