How a soda - acid type fire extinguish works.
Answers
✔✅The most common fire extinguisher is soda acid. The carbon dioxide is liberated by the action of acid on baking soda. ... The principle behind this type of portable extinguisher was tartaric acidmixed with a solution of sodium bicarbonate, which produced carbon dioxide to act as a propellant gas.
It contains an acid in a glass bottle and solid sodium hydrogen carbonate outside it. On striking The Fire extinguisher against hard surface, the glass bottle breaks and the acid mixes with sodium hydrogen carbonate. The CO2 gas, being heavier than oxygen covers the burning objects like a blanket. Since the contact between the fuel and oxygen is cut off, the fire gets controlled. Also, CO2, when released from the cylinder expands enormously in volume and cools down. So it not only forms a blanket around the fire,it also brings down the temperature of the fuel. It is therefore an excellent fire extinguisher.
