Sodium bicarbonate

Sodium bicarbonate (NaHCO3), which is inappropriately called sodium acid carbonate, is a basic salt, non-toxic and reacts with water, releasing carbon dioxide (CO2) and forming sodium hydroxide (NaOH).

This salt acts as an active ingredient in most effervescents used to combat stomach hyperacidity and thrush.

In cooking, it is widely used as baking cake and bread.

It can still be found in dry or wet powder fire extinguishers.
