Partition equilibrium is a special case of
The time until a partition equilibrium emerges is influenced by many factors, such as: temperature, relative concentrations, surface area of interface, degree of stirring, and the nature of the solvents and solute.
Example
For example,
- Kc = [NH3 (CHCl3)]/[NH3 (aq)] (where Kc is the equilibrium constant)
The equilibrium concentrations of ammonia in each layer can be established by titration with standard acid solution. It can thus be determined that Kc remains constant, with a value of 0.4 in this case.
Partition coefficient
This kind of equilibrium constant measures how a substance distributes or partitions itself between two immiscible solvents. It is called the partition coefficient or distribution coefficient.
