Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Importance: This massive text by outstanding research workers begins with simple systems and proceeds logically to the more complex phenomena of physical chemistry. The original literature is cited extensively, making the work useful as a reference as well as a textbook. Many topics of current research are treated.
