What chemicals are used in a fire extinguisher?

Answer 1

Most often, simple fire extinguishers use sodium carbonate and dilute sulfuric acid to produce carbon dioxide, that extinguishes fire. small pouch carries the acid within a matrix of sodium carbonate. The pouch prevents the acid to come in contact with sodium carbonate outside. When the bottle is shaken, the two chemicals come in contact with each other, liberating carbon dioxide and water droplets that extinguishers.

Another type of fire extinguisher contains compressed Carbon Tetrachloride in it. When the nozzle is pushed, an aerosol of carbon tetrachloride is liberated that suppresses and extinguishes fire. This type has a major advantage that it can extinguish fires of oils, electric circuits, etc.

Other forms of fire extinguishers use forced water to extinguish fire.

Answer 2

The main chemical used in fire extinguisher is carbondioxide(CO2). The reason is that it doesnot support combustion.(Combustion is the reaction of any chemical with oxygen O2

Answer 3

In fire extinguishers, they put carbon dioxide in it because it extinguishes fires. The two ingredients of carbon dioxide are; baking soda and vinegar.

Answer 4

Many fire extinguishers use CO2 to put out the fire, CO2 is very effective because it removes any atom of Oxygen around the fire and since a fire need oxygen to burn, it turns off.

Answer 5

A normal household extinguisher usually holds and propels nitrogen/carbon Dioxide. The active ingredient is usually Potassium Bicarbonate
