Collection of gasses
- 2. * * The Collection of a gas depends on two factors: ?Density of the gas ?Solubility in water
- 3. * *There are three methods of collecting gases: *Displacement of water *Upward Delivery *Downward Delivery
- 4. * *This is the best method to collect a gas when it is insoluble in water. Whether lighter or heavier than air if gas is insoluble this method can be used easily.
- 5. * *A gas that is less dense than air can be collected by upward delivery. Examples of gases that can be collected by this method are ammonia and hydrogen.
- 6. * *A gas that is more dense than air can be collected by downward delivery. Examples of gases that can be collected by this method are carbon dioxide, chlorine, hydrogen chloride and sulfur dioxide.
