Which acid is used in fire extinguisher?

The reaction of sulfuric acid with baking soda liberated carbon dioxide, which increases the percentage of carbon dioxide. Hence, the sulphuric acid is used as in fire extinguishers.

Is HCL used in fire extinguisher?

In the above reaction hydrochloric acid is used as acid and NaHCO3 is used as metal hydrogen carbonate to react with each other which produces carbon dioxide gas. 5) Therefore, Metal hydrogen carbonate is used with acid in a fire extinguisher to produce carbon dioxide gas which shows option B as the correct choice.

Why is acid used in fire extinguisher?

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).

What is used in fire extinguishers *?

Three types of extinguishing agents are typically used—carbon dioxide, dry chemical, and foam water for fires involving flammable liquids, greases, and oils. Carbon dioxide is a compressed gas agent that prevents combustion by displacing the oxygen in the air surrounding the fire.

Is sulphuric acid used in fire extinguisher?

The reaction of sulfuric acid with baking soda liberated carbon dioxide, which increases the percentage of carbon dioxide. Hence, the sulphuric acid is used as in fire extinguishers.

Is nitrogen used in fire extinguishers?

Nitrogen gas has long been used in the fire suppression industry. Its primary use has been as a pressurization gas in total-flood fire suppression systems and in portable fire extinguishers.

Why sodium bicarbonate is used in fire extinguisher?

Sodium bicarbonate is used in fire extinguishers because carbon dioxide is produced when it reacts with the high heat of the fire.

Why is sodium hydrogen carbonate used in soda acid fire extinguisher?

When the fire extinguisher is operated by pressing the knob on it, the sulphuric acid gets mixed with sodium bicarbonate solution producing a lot of carbon dioxide gas. 3. Carbon dioxide gas is neither combustible nor helps combustion. … Hence, sodium bicarbonate is used in fire extinguishers.

Which gas is used in fire?

Carbon dioxide is primarily suitable for fighting fire classes B and C. Due to its physical properties, carbon dioxide is the only extinguishing gas that is also used in fire extinguishers and fire extinguishing devices.

What chemicals are in fire extinguishers?

The most common agents used in dry chemical fire extinguishers are monoammonium phosphate and sodium or potassium bicarbonate. Time is of the essence when this type of extinguisher is used because these powders can be corrosive to metals and can lead to further damage if not cleaned up quickly.

Which chemical is used in foam fire extinguisher?

Aluminium sulphate is used in ‘foam’ fire extinguishers, which contain radium bicarbonate and aluminium sulphate in separate receptacles on being mixed they form the foam of bubbklkes of CO2.

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

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. … It is heavier than air and cuts off the air’s supply of oxygen, thus extinguishing the flames.

When so2 dissolves in water the acid formed is?

When sulphur dioxide is dissolved in water it forms sulfurous acid.
