Azeotropism for ethyl alcohol-water system disappears by_____________________?
Correct answer: B. Decreasing pressure
- A. Increasing temperature
- B. Decreasing pressure
- C. Increasing pressure
- D. No means
Explanation
The ethanol-water azeotrope can be removed by reducing pressure sufficiently, because azeotropic composition depends on pressure. This is the basis of pressure-swing separation.
