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.
Examples
- A replacement reaction concerning zinc metal and hydrogen chloride:
- Zn + 2 HCl → ZnCl
2 + H
2 (gas) - In this example, hydrogen gas in diatomic form is released.
- A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative):
- 2 HCl + F
2 → 2 HF + Cl
2 (gas)
gollark: Ah.
gollark: I have no idea what a DDP is.
gollark: I'm sure you can find interesting safe things to do. Or eventually learn how to do it safely.
gollark: Seems about right.
gollark: Don't have one, am a student.
