Electrochemistry Debye-Hiickel theory

Petrus (Peter) Josephus Wilhelmus Debye (1884-1966). .. was a Dutch physicist and physical chemist, who worked in the fields of quantum physics, X-ray analysis, microwave spectroscopy, and electrochemistry. Colloid science benefits from his contribution to X-ray and light scattering (in particular for aggregates— Eq. (4.39)— and concentrated suspensions—Eq. (2.24)), his work on electrolyte solutions (Debye-Hiickel theory), as well as his remarks to electrophoresis and his research on polymers. He was awarded the Nobel Prize in Chemistry in 1936 for his work on molecular structure through his investigations on dipole moments and the diffraction of X-rays and electrons in gases . 

A full mathematical derivation of Debye-Hiickel theory Is given in Chapter 2 of Electrochemistry ty P.H, Rieger, published by Prentice-Hall, New Jersey (1987), to which the mathematically inclined reader is directed. 

In all other solutions the so called degree of dissociation, as determined from the measurement of some colligative property, merely indicates the magnitude of interionic forces, it cannot, however, be taken as a measure of the quantity of dissociated and undissociated molecules of the solute. A complete theory of strong electrolytes, at least of their diluted solutions, has been developed by Debye and Hiickel, this theory is the basis of modern electrochemistry.
