The Nernst–Planck equation is a conservation of mass equation used to describe the motion of a charged chemical species in a fluid medium. It extends Fick's law of diffusion for the case where the diffusing particles are also moved with respect to the fluid by electrostatic forces. It is named after Walther Nernst … Ver mais The Nernst–Planck equation is a continuity equation for the time-dependent concentration $${\displaystyle c(t,{\bf {x}})}$$ of a chemical species: where Ver mais The Nernst–Planck equation is applied in describing the ion-exchange kinetics in soils.
