Q. No.The boiling point of an azeotropic mixture of water and ethanol is less than that of water and ethanol individually. The mixture shows:
1. No deviation from Raoult's law
2. Positive deviation from Raoult's law
3. Negative deviation from Raoult's law
4. That the solution is unsaturated
The azeotropic mixture of water and ethanol boils at 78.15 oC. When this mixture is distilled, it is possible to obtain-
1. Pure H2O
2. Pure C2H5OH
3. Pure H2O as well as pure C2HOH
4. Neither H2O nor C2H5OH in their pure state
