When a solute is shaken in two immiscible liquids it partitions itself between the two liquids in a definite ratio called the...?
What does the value of the partition coefficient depend on?
- The immiscible liquids involved
- The solute
- The temperature
What is an application of the partition of a solute beetween two liquids?
What is an application of solvent extraction?
The purification of water
What do chromatographic separations depend on?
The partition equilibrium between two phases - one stationary and the other mobile
What are examples of different types of chromatography?
- Paper chromatography
- Gas liquid chromatography
In paper chromatography, what are the stationary and mobiler phases?
- Stationary - the water held on the paper
- Mobile - Another solvent
In gas liquid chromatography, what are the stationary and mobile phases?
- Stationary - a liquid held on a solid support
- Mobile - a gas
What is the formula used to work out the Rf value?
Rf = distance travelled by compound / distance travelled by solvent
