Question

how does a sodium carbonate extinguisher work? can it be used to put off electric fires?

Answer 1

It consists of a cylinder filled with a solution of sodium bicarbonate. there is also a capsule of dilute sulphuric acid in it. When the knob is pressed, the acid in the capsule spills on the sodium bicarbonate. As a result of the chemical reaction that takes place, carbon dioxide is produced and it gushes out of the cylinder and as carbon dioxide neither burns nor supports burning it extinguish fires .
