Why can sodium hydrogen carbonate be used as an antacid?

Answer and explanation

Correct answer: Because it is mildly basic and neutralises excess acid

Sodium hydrogen carbonate, NaHCO₃, is a mild base. In the stomach it reacts with excess hydrochloric acid in a neutralisation reaction: NaHCO₃ + HCl → NaCl + H₂O + CO₂. This reduces excessive acidity, so option A is correct. It does not increase stomach acid, make water acidic, or act by dissolving tooth enamel. Its use should still be controlled because the reaction releases carbon dioxide and adds sodium.
