Question

Explain the structure, principle,and working of soda acid fire extinguisher?​

Answer 1

Answer:

Explanation:

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).

Answer 2

A soda-acid type of fire extinguisher contains a solution of sodium hydrogen carbonate and sulphuric acid in separate containers inside them. When the knob of the fire extinguisher is pressed, then sulphuric acid mixes with sodium hydrogen carbonate solution to produce carbon dioxide gas which forms a blanket around the burning substance and cuts off the supply of air to the burning substance. This stops the process of burning and fire gets extinguished.
