Vedclass · Answer

(C) Soda-acid fire extinguishers work on the principle of the reaction between an acid and a carbonate or bicarbonate salt. They contain a solution of $NaHCO_3$ (sodium bicarbonate) and a separate bottle of $H_2SO_4$ (sulfuric acid). When the extinguisher is activated,the acid reacts with the bicarbonate to release $CO_2$ gas,which helps in extinguishing the fire. Therefore,the correct component is $NaHCO_3$.

Fire extinguishers contain $H_2SO_4$ and which one of the following?
