Which of the following substance can be used to make a fire extinguisher?
A fire-extinguisher generally consists of baking soda and vinegar. The role of a fire extinguisher is to extinguish the fire by releasing carbon-dioxide which does not support combustion. So, the reaction which is the principle behind the working of fire extinguisher is the reaction between an acid and a metal bicarbonate. Acids react with a metal bicarbonate to form a metal salt, carbon-dioxide gas and water.
Acid(aq)+Metal Bicarbonate(s)→Metal Salt(s)+H2O(l)+CO2(g)
The reaction between acetic acid and baking soda is:
