Soda fire extinguisher uses sulphuric acid and sodium bicarbonate. It is very effective for usage in home.

In soda-acid fire extinguishers, sodium bicarbonate (NaHCO₃) and sulfuric acid (H₂SO₄) are both used.
It is the best fire extinguisher to use at home.

Working

Sodium bicarbonate (NaHCO₃) in water solution and sulfuric acid (H2SO₄) in a separate bottle are both present in the fire extinguisher.
Sulphuric acid combines with sodium bicarbonate solution when the fire extinguisher’s knob is turned, resulting in the production of a small amount of carbon dioxide gas (CO₂).
A non-combustible gas that does not support combustion is carbon dioxide.
Since it is heavier than air, it prevents the air from receiving oxygen, putting out the flames.
The response is manifested as:

2NaHCO₃(aq) + H₂SO₄(aq) → Na₂SO₄(aq) + 2H₂O(l) + 2CO₂(g)

Table of content

Fire extinguishers come in a wide range depending on how they change any of the factors from the fire triangle that they manage, including:

Foam and water: Removes oxygen and heat from the environment.
Carbon Dioxide: Removes the oxygen element and heat.
Dry Chemical: Stops the chemical process that is causing the fire.
Wet Chemical: Eliminates the heating element and prevents the re-ignition of the fuel and oxygen.
Clean Agent: Stops the fire’s chemical process.
Dry Powder: Removes heat and separates fuel from oxygen.
The hot element is removed by the water spray.
Dry chemical cartridge operation: Stops the fire’s chemical process.

Summary:-

Sodium bicarbonate and sulfuric acid are used in soda fire extinguishers. When used at home, it works quite well.
