| 11. | By calculating the mean activity coefficients from them the theory could be tested against experimental data.
|
| 12. | The Nernst equation for the distribution of the anion, ignoring the activity coefficients is written.
|
| 13. | The activity coefficients for silver and chloride are 0.75 and 0.76, respectively.
|
| 14. | More generally, the mean activity coefficient of a compound of formula A " p"
|
| 15. | Where " a " is the activity, and the ? are thermodynamic activity coefficients.
|
| 16. | In this situation the mean activity coefficient is proportional to the square root of the ionic strength.
|
| 17. | Where activity coefficients are not available, the coefficient may be assumed to be 1.0.
|
| 18. | A typical group contribution method using group interaction values is the UNIFAC method which estimates activity coefficients.
|
| 19. | The ^ \ dagger symbol has been used here to dinstinguish between the two kinds of activity coefficients.
|
| 20. | Single-ion activity coefficients can be calculated theoretically, for example by using the Debye H�ckel equation.
