Question

Explain Debye–Hückel Onsagar Law of the strong electrolyte.

Answer 1

Debye–Hückel Onsagar law

• Debye–Hückel limiting law is used to determine the behaviour of strong electrolyte.
• It is not applicable to weak electrolytes.
• Mathematically, it is written as
• ${\wedge }_c={\wedge }_0-bC$

Where,

${\mathrm{\Lambda }}_0$ is the limiting molar conductivity

b is the empirical constant

C is the electrolyte concentration

This theory was not applicable for the solution having higher electrolyte concentrations or with the electrolyte which produces ions of higher charges which are particularly unsymmetrical electrolytes.
