Why are the activity coefficients of ions calculated with the Debye Huckel theory always less than one?

Q10. 4) Why are activity coefficients calculated using the Debye–Hückel limiting law always less than one? The activity coefficients are less than one because the charge on an electrolyte lowers the chemical potential of the electrolyte when compared with an analogous solution of uncharged solute molecules.Click to see full answer. Hereof, why are activity coefficients calculated using the Debye Hückel limiting law always less than one?Activity coefficients calculated using the Debye-Hückel limiting law are always less than one because the net electrostatic interaction among ions surrounding an arbitrarily chosen central ion is attractive rather than repulsive.Additionally, how do you use activity coefficients? Ions carry an associated ionic atmosphere which must be factored into equilibrium calculations which use concentration. The activity coefficient is formed from calculating the ionic strength and effective ionic size. The activity coefficient can also be found from a table of known activity coefficients. Regarding this, what is Debye Huckel theory of strong electrolyte? The Debye-Hückel theory is based on three assumptions of how ions act in solution: Electrolytes completely dissociate into ions in solution. Solutions of Electrolytes are very dilute, on the order of 0.01 M. Each ion is surrounded by ions of the opposite charge, on average.What is the difference between activity and activity coefficient?Activity is a measure of the effective concentration of a species under non-ideal (e.g., concentrated) conditions. The activity coefficient is used to show how much the solution deviates from the ideal.
