activity coefficient

The number by which the concentration must be multiplied to give activity.


charge balance

A statement that the sum of all positive charge in solution equals the magnitude of the sum of all negative charge in solution.


extended Debye-Huckel equation

Gives the activity coefficient as a function of ionic strength.


ionic atomsphere

The region of solution around an ion or a charged particle. It contains an excess of oppositely charged ions.
