A person has indigestion due to excess acidity. Which substance would be most suitable for relief?
Answer and explanation
Correct answer: Mild basic antacid
Indigestion associated with excess acidity involves an unnecessarily high concentration of hydrochloric acid in the stomach. A mild basic antacid reacts with and neutralises some of this acid, raising the pH toward a less irritating value. It must be mild because a strong alkali could damage tissues. More hydrochloric acid would worsen the condition, while sugar and carbon dioxide do not neutralise stomach acid. Therefore A is correct.
