Q: When baking soda and water are mixed, can you boil out the water to end with baking soda in the pot?

Flexi Says: Baking soda is sodium bicarbonate that reacts when dissolved in water and forms CO₂ as gas. When the solution is heated the decomposition reaction takes place: NaHCO₃ + H₂O → NaOH + CO₂ +H₂CO₃ The carbonic acid is further decomposed on heating: H₂CO₃ → H₂O + CO₂ Heating the solution until the evaporation of water is complete leaves the decomposed sodium hydroxide only.
