Which substance gives relief during excess acidity in the stomach?
Answer and explanation
Correct answer: Antacid
Excess hydrochloric acid in the stomach can cause irritation and a burning sensation. An antacid contains a mild base, such as magnesium hydroxide, which reacts with and neutralises some of the excess acid. This raises the pH toward a less acidic value and provides relief. A strong acid would worsen acidity, while common salt and a metal are not suitable antacids. Hence option A is correct.
