Question

What are the components of a soda-acid extinguisher? How does it work to extinguish fire?
​

Answer 1

Answer:

ground, the acid bottle breaks and the acid comes in the contact with the backing soda. As a result carbon dioxide is liberated. This increases the percentage of carbon dioxide in air. Due to this the supply of air is cut off and there, fire is extinguished.

Answer 2

$\huge\bold\green{Answer}$

The working principle of any fire extinguisher is based on the following three conditions:

cooling of the combustible material below its ignition temperature

cutting off the air supply

cooling the combustible material simultaneously while cutting off the air supply.

This type of fire extinguishers acts on all fires except the fire caused due to electrical and inflammable liquids. It is the most effective of all house-hold fire extinguisher. Soda acid fire extinguisher contains sodium bicarbonate and sulphuric acid. It comprises of a strong iron vessel with a side discharge nozzle. The iron vessel is loaded with sodium bicarbonate solution. Sulphuric acid is supported in a small glass bottle and is kept inside the iron vessel. On striking the knob fixed just above this bottle, the acid bottle breaks open into the sodium bicarbonate solution. This broke open sulphuric acid reacts with sodium bicarbonate to form sodium sulphate, water and carbon dioxide. This carbon dioxide gas projects the enclosed liquid toward the flames successfully extinguishing it.
