Non-aqueous solvents ate bccommg 1ncrcasmgly used m clusnt1tat1ve mcasurc- nwnts, particularly in physical organic chemistry, clectrochcmistry and analytical chcmlstry. 13ccausc tlic rclcvant information 1s w wdcly scattered, the source of information provided by this volume is of great 1mportJnce

The general problems discussed in this volume concern Lewis acid-base intcr- actions m polar solvents (D. W Morrrc), solvat1on of clectrolytcs ancl solution cqulllbrla (E. PRICII), and acrdtty functions in amphlprotic solvents (13. G BATES) Expcrlmental results ale sumrnar1zcd and 1nterprctcd 1n chapters on elcctrodc potcntlal (H S TREH-

LOW) and on solvent extraction of inorganic spcc1cs (L I KA~ZIX). Experlmcntal technques we chscusscd 1n chapters on hancllmg low-bo1lmg solvents (J N~sstw~) and fusecl salts (12. A I~AILEY AND G. .J. JANZ).

Tile rcv1cw\ are well clocumcntccl and the lltcrature 1s covered to about 1964

The writing 1s authoritative ancl lucid and the editing appears to have been clone very well. This book can bc recommcnclecl to analytical cllemlsts as a valuable source of information.
