This article tries to offer an overview of some basic laws of thermodynamics and electrostatics which are considered to be part of the foundations of electrochemical thinking. Equilibrium thermodynamics is introduced in terms of conservation laws paying particular attention to the notion of chemical potential. After discussing the forces, potentials, and energetics of charges in vacuum the same problems are dealt with in continuous dielectric media. Here polarization, formation and role of dipole moments, their relation to relative permittivity (dielectric constant) are discussed both in macroscopic and atomic/molecular terms. Finally the kinetics of the response of relative permittivity to the variation of polarizing fields and charges are described. Solvation processes are referred to in connection with both thermodynamic and electrostatic considerations.
