9. (4 pts.) When refluxing, a mixture of toluene and water is refluxing and condensing in the Hickman still head. A specific mixture of toluene and water will actually boil at a LOWER TEMPERATURE then either pure toluene or pure water. This is the azeotrope mixture, toluene and water can from an azeotrope. The practical consequence of this is that the toluene solvent will always have at least some water in it when it boils, which is how we are...
