Question

Carbon dioxide is used in fire extinguisher.

• A. True
• B. False

Answer 1

The correct option is A True

Carbon dioxide is used in fire extinguisher, the release of gas under pressure has a cooling effect.
$N{a}_{2}C{O}_3+H_{2}S{O}_4\to N{a}_{2}S{O}_4+H_{2}O+C{O}_2$In the inner part of the extinguisher, the whole container is filled with the strong solution of sodium carbonate and there is a glass tube in the bottom of the container contains sulfuric acid. The glass tube is broken with a powerful pressure when required. And the solutions are reacted with each other and carbon dioxide is produced. Then the $C{O}_2$ is released through the tiny hole in a very high pressure and extinguishes the fire.
