Question

what is soda acid fire extinguisher?

Answer 1

Dear student!

Soda acid fire extinguisher is the mixture of sodium bicarbonate and an acid which is generally sulphuric acid however, initially tartaric acid was used. The acid and sodium bicarbonate react together to form the water, carbon dioxide gas and sodium sulphate and the carbon dioxide gas comes out with water in the form of fountain under pressure and that acts as a fire extinguisher as:

2NaHCO₃ + H₂SO₄ -> Na₂SO₄ + 2H₂O + 2CO₂
