| 1. | It is calibrated against buffer solutions of known hydrogen ion activity.
|
| 2. | For example, pH is defined as the negative logarithm of the hydrogen ion activity.
|
| 3. | Debye and H�ckel developed a theory with which single ion activity coefficients could be calculated.
|
| 4. | Single-ion activity coefficients can be calculated theoretically, for example by using the Debye H�ckel equation.
|
| 5. | Expressions were derived for the variation of single-ion activity coefficients as a function of ionic strength.
|
| 6. | This led to the development of what is now called the free-ion activity model ( FIAM ).
|
| 7. | PH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, " a"
|
| 8. | Firstly, the cell is filled with a solution of known hydrogen ion activity and the emf, " E"
|
| 9. | However, chemists have never been able to give up the idea of single ion activities, and by implication single ion activity coefficients.
