Answer:
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).

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
