How soda acid and type extinguisher work?
Answers
SodaAcidTypeFireExtinguisher:-
\implies⟹ A Soda-Acid type Fire Extinguisher works in Following manner :
\star⋆ It contains an acid in a glass bottle and solid sodium hydrogen carbonate outside it. On striking the fire extinguisher against a hard surface,the glass bottle breaks and the acid mixes with Sodium Hydrogen Carbonate. The reaction occurs in following way :
2NaHCO3 + H2SO4 \implies⟹ Na2SO4 + 2H2O + 2CO2
\star⋆ The CarbonDioxide Gas being heavier than oxygen,Covers the burning objects like a blanket. Since the contact between the fuel and the oxygen is cut off,the fire gets controlled. Also,Carbondioxide Gas when released from the Cylinder expands enormously in volume and cools down. It also beings down the temperature of the fuel. It is, Therefore an excellent fire Extinguisher
Answer:
Soda acid type extinguisher acts by cutting off supply of air. It acts on all types of fire except due to electrical and inflammable liquids. 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).
