Example Values
Example values of activity coefficients of sodium chloride in aqueous solution are given in the table. In an ideal solution, these values would all be unity. The deviations tend to become larger with increasing molality and temperature, but with some exceptions.
| Molality (mol/kg) | 25 °C | 50 °C | 100 °C | 200 °C | 300 °C | 350 °C |
|---|---|---|---|---|---|---|
| 0.05 | 0.820 | 0.814 | 0.794 | 0.725 | 0.592 | 0.473 |
| 0.50 | 0.680 | 0.675 | 0.644 | 0.619 | 0.322 | 0.182 |
| 2.00 | 0.669 | 0.675 | 0.641 | 0.450 | 0.212 | 0.074 |
| 5.00 | 0.873 | 0.886 | 0.803 | 0.466 | 0.167 | 0.044 |

Famous quotes containing the word values:
“The vulgar crowd values friends according to their usefulness.”
—Ovid (Publius Ovidius Naso)
“Our first line of defense in raising children with values is modeling good behavior ourselves. This is critical. How will our kids learn tolerance for others if our hearts are filled with hate? Learn compassion if we are indifferent? Perceive academics as important if soccer practice is a higher priority than homework?”
—Fred G. Gosman (20th century)
