His extinguisher used the reaction between sodium bicarbonate solution and sulfuric acid to expel pressurized water onto a fire.
Which acid and base is used in fire extinguisher?
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.
What chemical is in fire extinguishers?
Handheld extinguishers, which are commonly sold at hardware stores for use in the kitchen or garage, are pressurized with nitrogen or carbon dioxide (CO2) to propel a stream of fire-squelching agent to the fire.
Which acid and bases are present in fire extinguisher which product is formed and how it works Class 10?
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.
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 sodium bicarbonate is 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. … Carbon dioxide gas is neither combustible nor helps combustion. … Hence, sodium bicarbonate is used in fire extinguishers.
Is nitrogen gas 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 nitrogen is not used in fire extinguishers?
Nitrogen is not heavier than air, so it will not cover the fire so as to displace oxygen. Water works to put out fire because it cools the fuel down below its flash point, but it does not work on all fires, hence several types of extinguishers are made. Nitrogen gas does not absorb enough heat to have that effect.
Which salt is used in fire extinguisher?
Sodium bicarbonate is a chemical compound that is used in both fire extinguishers and antacids. Sodium bicarbonate, commonly known as baking soda, is a chemical compound with the formula . It is a salt made of a sodium cation and a bicarbonate anion.
Why is soda acid used as a 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 does soda acid fire extinguisher contains?
Hint: A soda acid fire extinguisher contains an acid and a hydrogen carbonate, which react together to form carbon dioxide gas and this gas is responsible for stopping the fire.
What are the 4 types of fire extinguishers?
There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire.
- Class A extinguishers will put out fires in ordinary combustibles such as wood and paper.
- Class B extinguishers are for use on flammable liquids like grease, gasoline and oil.
Is sodium carbonate a base or acid?
– Now, we know that sodium hydroxide is a strong base and carbonic acid is a weak acid. – Therefore, sodium carbonate is a basic salt because it is a salt derived from a weak acid and strong base.
Is sodium hydrogen carbonate acidic or basic?
We know that sodium hydrogen carbonate is a basic salt because its parent base is strong (NaOH) and parent acid is weak (H2CO3).
Is sodium hydrogen carbonate used in fire extinguisher?
Solution: Sodium hydrogen carbonate or sodium bicarbonate is used as a fire extinguisher. When heated to a high temperature, the chemical properties of this salt make it produce lots of carbon dioxide and remove oxygen. This reduces the amount of oxygen and puts the fire out.
