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).
To make a model of a soda acid fire extinguisher, you'll need a clear plastic bottle, baking soda, vinegar, and a small balloon. Fill the bottle with a few tablespoons of vinegar, then place a few teaspoons of baking soda inside the balloon without letting it fall into the bottle. Secure the balloon over the bottle's opening without letting the baking soda spill in. When ready to demonstrate, release the baking soda into the vinegar, which will create carbon dioxide gas and build pressure, simulating how the extinguisher works.
