| 21. | :something worth looking up for each will be the Partition coefficient, which will give you an idea of relative polarities.
|
| 22. | Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus changing the separation.
|
| 23. | The partition coefficient ( Log P ) is a measure of differential solubility of a compound in a hydrophilic solvent ( water ).
|
| 24. | If one of the solvents is a gas and the other a liquid, a gas / liquid partition coefficient can be determined.
|
| 25. | For example, the blood / gas partition coefficient of a general anesthetic measures how easily the anesthetic passes from gas to blood.
|
| 26. | The hydrophobic effect can be quantified by measuring the partition coefficients of non-polar molecules between water and non-polar solvents.
|
| 27. | The "'partition coefficient "'is the ratio of concentrations of un-ionized compound between the two solutions.
|
| 28. | The concentration in aqueous phase is now 5.6 * 10 ^-5 M and the new partition coefficient is 22.
|
| 29. | For nonionic organic contaminants, the K OC can be determined based on the octanol-water partition coefficient ( K OW ).
|
| 30. | Used widely in pharmaceutical research, LogD is the logarithm of the " true " partition coefficient of a compound between octanol and water.
