Baking soda, which is referred to as sodium bicarbonate in chemistry, is a weak base. Commonly used in baking, sodium bicarbonate ionizes weakly in water, which causes a release of carbon dioxide, making the baked item rise.
The chemical formula for sodium bicarbonate is NaHCO3. In chemistry, sodium bicarbonate is used to produce pure samples by acting as a wash that removes acidic impurities from crude liquids.
Other weak bases include ammonia and diethylamine. Unlike sodium bicarbonate, strong bases and acids are completely dissociated in water, while sodium bicarbonate is only partially dissociated in water. Examples of strong acids are sulfuric acid, hydrochloric acid, nitric acid and hydrobromic acid.
