Sodium bicarbonate is used in fire extinguishers due to its ability to produce carbon dioxide gas. Many fire extinguishers contain sodium bicarbonate, sulphuric acid, and water. When these substances are mixed together, the reaction produces carbon dioxide gas.
Sodium bicarbonate is used in most dry fire extinguishers. When dispensed, the products absorb heat, decompose to form fire smothering carbon dioxide , and release free radicals which interrupt the flame chain reaction mechanism.
How does sodium bicarbonate extinguish fires? – Quora
The fire extinguisher : It consists of a cylinder filled with a solution of sodium bicarbonate . there is also a capsule of dilute sulphuric acid in it. When the knob is pressed the acid in the capsule spills on the sodium bicarbonate. As a result of the chemical reaction that takes place, carbon dioxide is produced and it gushes out of cylinder ,and as carbon dioxide neither burns nor …
Sodium bicarbonate reacts with heat to become sodium carbonate. You need a pretty high temperature of more than 518 degrees Fahrenheit to create this reaction. This should happen easily when in contact with flames.

When these substances are mixed together, the reaction produces carbon dioxide gas. Simply so, why baking soda is used in fire extinguisher?
Why is baking soda used as a fire extinguisher?
Baking soda, (sodium bicarbonate) is used in class C fire extinguishers. When sodium bicarbonate (baking soda) is heated by the fire it becomes sodium carbonate. The carbon dioxide starves the fire of oxygen smothering the fire and the water that is released cools the heat source.
What happens when sodium bicarbonate is added to acid?
When the knob is pressed the acid in the capsule spills on the sodium bicarbonate. As a result of the chemical reaction that takes place, carbon dioxide is produced and it gushes out of cylinder ,and as carbon dioxide neither burns nor supports burning it extinguish fires .
What is the Ultimae effect of sodium bi carbonate on fire?
This reaction is thermodynamically endothermic (forward reaction). Thus ultimae effect of fire fighter becomes absorbing heat from the fire. Moreover, the melting point of sodium bi carbonate is quite high enough withstand the temperature.
