Soda acid type extinguisher acts by cutting off supply of air. It acts on all types of fire except due to electrical and inflammable liquids. 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).

Why baking soda is used in soda acid fire extinguisher?
Carbon dioxide gas is neither combustible nor helps combustion. It is heavier than air and cuts off the supply of oxygen from air and hence extinguishes the fire. … Hence, sodium bicarbonate is used in fire extinguishers.
How does soda acid fire extinguisher work write chemical reaction?
the bottle of the fire extinguisher contains concentrated sulphuric acid.it is attached to a knob. knob is struck for the chemical reaction to take place. the bottle breaks and sulphuric acid reacts with sodium bicarbonate. due to this reaction, carbon-dioxide is produced.
