Activity is the value that replaces concentration in a thermodynamically correct equilibrium expression. b) The activity coefficient measures the deviation from the ideal behavior and is the number by which the concentration must be multiplied to give activity. c) Ionic strength is a measure of the total concentration of ions in solution. The more charged an ion is, the smaller its participation in the calculation of ionic strength. d) When considering the effect of ionic strength on chemical reactions, we substitute activities for concentrations. e) The Debye-Hückel equation relates activity coefficients to ionic strength. In the equation we have: γ, activity coefficient of an ion of charge ± Ζ and size α, the value of α is the radius of the atom, in an aqueous solution of ionic strength μ
