Question

what is the principle of Soda acid extinguisher

Answer 1

Working of Soda- Acid Fire Extinguisher:

The container of soda acid fire extinguisher holds a sodium bicarbonate solution.

The screw-on cap contains a plunger mechanism which is covered by a safety guard. Below the plunger is a glass phial containing sulphuric acid.

When the plunger is struck, the glass phial is broken and the acid and sodium bicarbonate mix together

The resulting chemical reaction produces carbon dioxide gas which pressurises the space above the liquid forcing it out through the internal pipe to the nozzle.(see image)
