Why You Absolutely Should Not Use Baking Soda as an

Oct 24, 2013Baking soda's chemical name is sodium bicarbonate, and bicarbonate is an amphiprotic ion, so it can both take and lose a hydrogen ion. So, this means that baking soda reacts with acids and bases by either donating or accepting a hydrogen ion. But bicarbonate is a stronger base than it is an acid, so it's more likely to accept a hydrogen.
