Which of the following are the constituents of a soda acid fire extinguisher?
Detailed Explanation:
Soda acid fire extinguisher contains dilute sulphuric acid (H₂SO₄) and sodium bicarbonate (NaHCO₃) solution in separate compartments.
When activated, the acid reacts with sodium bicarbonate: 2NaHCO₃ + H₂SO₄ → Na₂SO₄ + 2H₂O + 2CO₂, producing carbon dioxide gas that smothers the fire by cutting off oxygen supply.
Option 3 is correct.
