Question

How was soda fire extinguisher help in putting out a fire?

Answer 1

Soda acid fire extinguisher contains sulphuric acid and sodium hydrogen carbonate which react to form water and CO2 which extinguish fire.The reaction is as follows:
H2SO4+2NaHCO3----->2H20+2CO2

Answer 2

A fire extinguisher is a fire protection device used to extinguish or control small fires. It usually consists of a hand held cylinder containing an agent which can be discharged to extinguish fire. The main principle of fire extinguishers is to cut off the supply of oxygen which is a supporter of combustion. This is done by increasing the level of CO2which is a non supporter of combustion and therefore the fire ceases. This CO2 is produced by the reaction between soda and acid. The mixture used in soda-acid fire extinguisher is Sodium bicarbonate solution and Sulphuric acid.The reaction is as follows:
2NaHCO3+ H2SO4→Na2SO4 + 2H2O + 2CO2

The fire extinguisher contains sodium bicarbonate in a container. A small glass bottle below the plunger contains sulphuric acid. This glass bottle is covered with a safety glass. When we want to extinguish a fire, we need to strike the plunger hard enough so that the glass breaks releasing sulphuric acid which reacts with sodium bicarbonate and produce carbon dioxide. The carbon dioxide gas produced under pressure forces itself through nozzle. As the percentage of carbon dioxide increases, the oxygen supply is reduced and therefore the fire extinguishes.
