A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide. Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or are explosive.
Eg. A replacement reaction concerning zinc metal and hydrogen chloride:
Zn + 2 HCl → ZnCl2 + H2 (gas)
In this example, hydrogen gas in diatomic form is released.
