How do you remove benzene from water?
No major effort required. Pipet water out and leave benzene behind. ;)
Benzene is highly symmetrical (
Although both benzene and water can perform London dispersion, benzene is again, highly symmetrical, which makes it very hard to polarize to generate even an induced dipole.
Since one of the requirements for solvation is similar intermolecular forces, benzene does not fare well. Thus, there is good reason to believe that benzene is poorly soluble in water.
In fact, the solubility of benzene is
The density of benzene is
Squeeze the pipet bulb before immersing it, then immerse it until you reach the bottom, and grab the water until you have a very thin layer of water left (go slowly).
