Debye factor

WebMar 24, 2024 · Peter Debye was born in Maastricht, Netherlands. His father, Johannes Wilhelmus Debije (1859-1937), was a foreman at the J. G. Lambriex metal goods factory and his mother, Maria Anna Barbara Ruemkens (1859-1940), a cashier at the theatre. WebDebye and Hückel came up with a theoretical expression that makes is possible to predict mean ionic activity coefficients as sufficiently dilute concentrations. The theory considers the vicinity of each ion as an atmosphere-like cloud of charges of opposite sign that cancels out the charge of the central ion (Figure 25.6. 1 ).
