You asked: Why are washing soda and sulphuric acid used in fire extinguishing machine?

There is a solution of sodium bicarbonate in water in the fire extinguisher and sulphuric acid in a different bottle within it. The sulphuric acid is combined with sodium bicarbonate solution and creates an amount of carbon dioxide gas when the fire extinguisher is operated by turning the knob on it.

Why is sulphuric acid kept in fire extinguisher?

When the knob of the fire extinguisher is opened, the sulphuric acid reacts with sodium bicarbonate producing a large amount of carbon dioxide. As carbon dioxide is non-combustible and heavier than air, it cuts off the air supply of the oxygen and extinguishes the flame.

How is baking soda useful in soda acid fire extinguisher Support your answer with a balanced chemical equation?

Answer: Soda acid fire extinguisher acts by cutting off supply of air. The carbon dioxide is liberated by the action of acid on baking soda ,it increases the percentage of carbon dioxide in air (as it is a non supporter of combustion)

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.
