Soda-acid fire extinguishers comprises of sodium bicarbonate and sulphuric acid. It is the most efficient house-hold fire extinguisher. It consists of a strong iron vessel with a side discharge nozzle. The iron vessel is filled with a sodium bicarbonate solution.
What does a 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 chemical ingredients are present in fire extinguisher?
Carbon dioxide is a compressed gas agent that prevents combustion by displacing the oxygen in the air surrounding the fire. The two types of dry chemical extinguishers include one that contains ordinary sodium potassium bicarbonate, urea potassium bicarbonate, and potassium chloride base agents.
Which salt is used in soda acid fire extinguisher?
The correct answer is Sodium Hydrogen Carbonate. Soda-acid fire extinguishers comprise sodium bicarbonate or Sodium Hydrogen Carbonate and sulphuric acid. It is the most efficient house-hold fire extinguisher.
Which substance is used in the formation of carbon dioxide in the soda acid fire extinguisher?
Carbon dioxide is a common propellant, brought into play by removing the locking pin of the cylinder valve containing the liquefied gas; this method has superseded the process, used in the soda-acid fire extinguisher, of generating carbon dioxide by mixing sulfuric acid with a solution of sodium bicarbonate.
What is the common name of sodium bicarbonate?
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3.
Why baking soda is used in soda 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.
How do you make a soda acid fire extinguisher?
Make the Fire ExtinguisherFill the jar about halfway full with vinegar. To activate the fire extinguisher, drop in a spoonful of baking soda. Immediately shake the jar and point the hole of the jar toward your fire. Test out your fire extinguisher on a candle or small intentional fire so you will know what to expect.
