Project Details:

Glossary of terms related to solubility - updates and revisions to the Orange Book

This project will produce a set of Recommendations for publication in PAC and replace the existing Section 3.2.5 of the Compendium of Analytical Nomenclature (the Orange Book). The new text in glossary format will cover terminology related to the solubility of gases in liquids, liquids in liquids and solids in liquids.

Clear and consistent use of agreed-upon terminology and nomenclature is essential for unambiguous scientific communication. For many years IUPAC has carefully prepared recommendations for terminology and nomenclature related to the various branches of chemistry. These recommendations are disseminated to the international community of chemists and users of chemical information, by publication in Pure and Applied Chemistry (PAC) and as a series of monographs collectively known as the "color books" including the Compendium of Analytical Nomenclature (the Orange Book, itself a collection of recommendations previously published in PAC). In recent years the color books have begun a migration to the world wide web where their content is readily accessible to a broader audience than was possible for the bound volumes.The existing section of the Orange Book that treats solubility equilibria (3.2.5) is quite brief and limited to the aqueous solubility of ionic substances. This project will revise, expand and update this section with a comprehensive treatment of terminology related to solubility including the solubility of gases in liquids, liquids in liquids, and solids in liquids.

The Task Group preparing this revision is drawn from members of the Subcommittee of Solubility and Equilibrium Data and participants in the Solubility Data Project. Thus the Task Group consists of an international group of solubility experts who are familiar with the procedural requirements of a project leading to IUPAC Recommendations. In addition the Task Group members have access to a variety of IUPAC generated documents (Solubility Data Series Guideline for Compilers, Evaluators and Editors; Introductions to the Gas-Liquid, Liquid-Liquid, and Solid-Liquid Sub-series of the Solubility Data Series; and the Experimental Determination of Solubilities). These contain many important definitions of terms and constitute a partial first draft of the work.
