a soda acid fire extinguisher consist of concentrated sulphuric acid and baking soda (soda bicarbonate) . On pressing the knob,the sulphuric acid reacts with soda which forms sodium sulphate and water liberating CO2. this helps in the cutting of oxygen supply and thus extinguishes the fire.
What is the principle of soda fire extinguisher?
In a soda acid fire extinguisher, when the knob is struck concentrated sulphuric acid present in the fire extinguisher comes in contact with sodium bicarbonate and produces carbon dioxide that puts out the fire.
What are the components of soda acid extinguisher How does it work to extinguish fire?
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.
Why is baking soda used as 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.
What does a soda acid type fire extinguisher contain How does it work explain the working of a soda acid fire extinguisher with the help of a Labelled diagram?
A soda-acid type of fire extinguisher contains solutions of sulphuric acid and sodium hydrogencarbonate in separate containers. … When the knob of the fire extinguisher is pressed, the sulphuric acid mixes with the sodium hydrogencarbonate solution to produce a substantial quantity of carbon dioxide gas.
Which gas is used in soda acid fire extinguisher?
Reaction: 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.
What are the component of soda acid extinguisher?
Soda acid for extinguishers consists of sodium hydrogen carbonate and sulphuric acid. The reaction happening between Sodium bicarbonate solution and sulphuric acid exert pressurized water onto a fire.
Why is soda acid fire extinguisher not effective when oil catches fire?
(a) Soda-acid fire extinguisher is not successful in controlling fire due to oils because it uses water to cool the combustible substance. But water is heavier than oil and settles down below the oil particles and oil keeps on burning on the top. Hence, fire cannot be controlled.
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)
