The book entitled with "Solution Ionophoretic Technique in Study of Metal-Ligand Equilibria" deals with solution ionophoretic technique,which is used for the determination of the stability constants of metal complexes is better than other physiochemical methods but it has some vitiating factors (e.g. diffusion, ionic strength and temperature). This technique is free from these vitiating factors and results are fairly reliable. The technique used in these studies proved to be very useful in studying the stepwise complextion in solution. The special electrophoretic tube which has been designed for this work, yields better results after standardization. This technique provides vivid picturization of complex formation whose stability constant can be determined easily. Its further extension in the study of mixed complexation reactions is obviously a unique advancement in the realm of coordination chemistry.
