| Abstract: | It was pointed out that two terms should be contained in the ion activity coefficient expression in the frame of Debye-Hiackel theory, i.e. the electrostatic term and osmotic term. Particular attention has been paid to explorations for the meaning and role of the osmotic term in the theory of ionic solutions. |

| Keywords: | ion activity coefficient electrostatic term osmotic term |
