Quick Answer: What is the principle of soda fire extinguisher *?

a soda acid fire extinguisher consist of concentrated sulphuric acid and baking soda (soda bicarbonate) . On pressing the knob,the sulphuric acid reacts with soda which forms sodium sulphate and water liberating CO2. this helps in the cutting of oxygen supply and thus extinguishes the fire.

Which is the principle of soda fire extinguisher?

In a soda acid fire extinguisher, when the knob is struck concentrated sulphuric acid present in the fire extinguisher comes in contact with sodium bicarbonate and produces carbon dioxide that puts out the fire.
