The carbon dioxide is liberated by the action of acid on baking soda. It increases the percentage of carbon dioxide in air (CO2 is non supporter of combustion). This type of fire extinguisher contains a bottle of sulphuric acid supported by a metallic container filled with a baking soda solution.

The gas produced by the reaction of baking soda and acid which helps as fire extinguisher is carbon dioxide.
Explanation:
When baking soda (sodium bicarbonate, NaHCO3) reacts with an acid, it undergoes a chemical reaction called neutralization. During this reaction, carbon dioxide (CO2) gas is produced, along with water and a salt. The carbon dioxide gas is responsible for the fire extinguishing property of baking soda.
Reaction:
The reaction between baking soda and an acid can be represented by the following general equation:
NaHCO3 + HX → H2O + CO2 + NaX
In this equation, NaHCO3 represents baking soda, HX represents the acid, H2O represents water, CO2 represents carbon dioxide, and NaX represents the salt formed.
Fire Extinguishing Property:
Carbon dioxide is commonly used in fire extinguishers because it is a non-flammable gas that can displace oxygen, thereby suffocating the fire. When baking soda is used in a fire extinguisher, it reacts with the acid present in the extinguisher to produce carbon dioxide gas. The carbon dioxide gas then displaces the oxygen, creating an environment where the fire cannot sustain itself. This helps to extinguish the fire effectively.
Other Uses of Baking Soda:
Apart from its fire extinguishing property, baking soda has several other uses. It is commonly used as a leavening agent in baking, as it reacts with acids present in the recipe to produce carbon dioxide gas. This gas gets trapped in the dough or batter, making it rise and giving the baked goods a soft and spongy texture.
Additionally, baking soda can also be used as an antacid to relieve heartburn or indigestion. It reacts with the excess stomach acid to form carbon dioxide, which helps to neutralize the acid and provide relief.
In conclusion, carbon dioxide is the gas produced by the reaction of baking soda and acid, making it an effective fire extinguisher. Its non-flammable nature and ability to displace oxygen make it ideal for extinguishing fires.
