Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HC1), which the stomach secretes to help digest food. Drinking a glass of water containing dissolve NaHCO3 neutralizes excess HCl through this reaction: HCI(aq) NaHCO3(aq) → NaCl(aq) + H,O() + CO2(g) The CO2 gas produced is what makes you burp after drinking the...
