Answer 2

The chemical name and chemical formula of the salt used in soda-acid fire extinguisher is sodium bicarbonate (NaHCO₃)

• This fire extinguisher consists of an iron vessel filled with sodium bicarbonate (also called sodium hydrogen carbonate) solution.
• A certain amount of sulphuric acid is also present which reacts with the sodium bicarbonate salt when the extinguisher is turned on.

• The following reaction takes place:

        2NaHCO₃ + H₂SO₄ → Na₂SO₄ + 2CO₂ + 2H₂O

• As carbon dioxide is a non-combustible gas, it is effective in blocking the oxygen supply and extinguishing the flame.
