Sodium Bicarbonate

**Molecular formula:** NaHCO₃

**Molar mass:** 84,007 g/mol

**Information:** Sodium bicarbonate or edible soda is a basic, white, crystalline powder. It is an ionic compound formed with a sodium cation Na⁺ and a bicarbonate anion HCO₃⁻.

**Use:** It is used as a baking powder (thermal decomposition releases carbon dioxide which causes the dough to be strengthened: 2 NaHCO₃ → Na₂CO₃ + H₂O + CO₂). It is contained in some fire extinguishers.
