Explain soda fire extinguisher in short

 Soda- Acid Fire Extinguisher:-
• cooling the combustible material below its ignition temperature.
• cutting off the supply of air.
• cooling the combustible material and at the same time cutting the supply of air.

The most common fire extinguisher is soda acid. The carbon dioxide is liberated by the action of acid on baking soda. It increases the percentage of carbon dioxide in air (CO₂ is non supporter of combustion).

The container of soda acid fire extinguisher holds a sodium bicarbonate solution. The screw-on cap contains a plunger mechanism which is covered by a safety guard. Below the plunger is a glass phial containing sulphuric acid. When the plunger is struck, the glass phial is broken and the acid and sodium bicarbonate mix together . The resulting chemical reaction produces carbon dioxide gas which pressurises the space above the liquid forcing it out through the internal pipe to the nozzle.
