They have 2 Different chambers
1 contains in a glass vale sulfuric acid
2 Containes in the canister sodium bicarbinate
when you mix (by shacking or turning over or strike a plunger) they produce co2 wich expells the water out
excuse the spelling mistakes lol
It doesn't. The soda solution mixes with the acid and the chemical reaction FORMS carbon dioxide gas, which pressurizes the extinguisher.

A soda acid fire extinguisher uses water as a carrier of the soda/acid. A television fire is primarily an electrical fire. Adding water to an electrical fire will only complicate the problem by introducing the possibility of shorts and electrocution. bock442
It is the propellant used to force water out of the extinguisher.
hydrochloric acid and hydrogen
Currently silver colored, older ones are brass.
In older soda/ acid extigushers, it generated carbon dioxide gas that propelled water from the extinguisher. In modern dry chemical extinguishers, it is the extiguishing agent- the same CO2 gas cuts off the oxygen to the fire.
Acid can corrode the metal shell of the extinguisher. When it is rapidly pressurized, it may explode. They are no longer an approved extinguisher in many nations.
One OLDER style of extinguisher was filled with water and bicarbonate of soda (baking soda)- AND had a small bottle of an acid. When it was turned upside down, the acid ran out of the bottle, mixed with the soda, and produced carbon dioxide gas. The gas forced the water out under pressure. NOT USED ON MOST MODERN EXTINGUISHERS.
A soda-acid extinguisher expells water (actually a dilute sodium sulfate solution formed by the reaction of the soda and the acid). Therefore, it's used on the same types of fires as normal water extinguishers; wood, paper, textiles and so on. It must NOT be used on burning liquids (which would be splashed around, sperading the fire) or on live electrical equipment (becuse of the risk of electrocution).
baking soda
There are two kinds of fire extinguisher powders. The first is monoammonium phosphate, which you find in A-B-C dry chemical extinguishers. To make it, add phosphoric acid to ammonia water until the mixture turns acidic, and the monoammonium phosphate will crystallize out of solution. In B-C fire extinguishers you will find sodium bicarbonate. This is baking soda, and you can get that at any grocery store.
