| 1. | Nitric acid (68%) and water (32%) mixture is an example of the minimum boiling azeotrope. | 
| 2. | Osmosis can be reversed if pressure lower than the osmotic pressure is applied to the solution. | 
| 3. | As compared to other colligative properties, the magnitude of osmotic pressure is large even for very dilute solutions. | 
| 4. | The condition of anoxia in mountain climbers is an application of Raoult's law. |
