Born equation - Alchetron, The Free Social Encyclopedia

The Born equation is a means of estimating the Gibbs free energy of solvation of a gaseous ion. It is an electrostatic model that treats the solvent as a continuous dielectric medium (it is thus one member of a class of methods known as continuum solvation methods). It was derived by Max Born.

Δ G = − N A z 2 e 2 8 π ϵ 0 r 0 ( 1 − 1 ϵ r )

where:

N_A = Avogadro constant

z = charge of ion

e = elementary charge, 1.6022×10⁻¹⁹ C

ε₀ = permittivity of free space

r₀ = effective radius of ion

ε_r = dielectric constant of the solvent
