Chemistry:Gas evolution reaction
From HandWiki
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 dilute sulfuric acid.
- [math]\ce{ Zn + H_2SO_4 (dil) -> ZnSO_4 + H_2 ^ }[/math]
- In this example, diatomic hydrogen gas is released. Dilute hydrochloric acid can be used in place of dilute sulfuric acid.
- A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative):
- [math]\ce{ 2HCl + F_2 -> 2HF + Cl_2 ^ }[/math]
