Which substance is used to get relief from excess acidity?
Answer and explanation
Correct answer: Antacid (प्रतिअम्ल)
The governing concept is acid–base neutralisation in the stomach. Excess hydrochloric acid can cause acidity and discomfort. An antacid is generally a mild base, such as magnesium hydroxide, so it reacts with and neutralises some of the excess acid without being strongly corrosive. Hence option A is correct. An acid would increase acidity, while an ordinary neutral salt or a metal is not the standard substance used for this relief.
