Gas evolution reaction
A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide.[1][2] Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive.[3]
Examples
- A replacement reaction concerning zinc metal and dil. sulphuric acid .
- In this example, hydrogen gas in diatomic form is released. Dilute sulphuric acid can also be used in place of dilute hydrochloric acid.
- A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative):
