Debye theorie
Webdebye, sur le Wiktionnaire. Peter Debye (1884-1966) est un physicien et chimiste néerlandais. Plusieurs notions sont nommées en son honneur : la longueur de Debye, … WebABSTRACT: Peter Debye and Erich Hückel had developed a theory for the ionic activity coefficients in dilute solutions of strong electrolytes some 95 years ago [1]. Their limiting law still stands and is confirmed as close to reality in many experiments.
