Why does taking an antacid give relief when acidity increases in the stomach?
Answer and explanation
Correct answer: Antacid neutralises excess acid
Excess hydrochloric acid in the stomach can cause a burning sensation and indigestion. Antacids contain mild bases, such as magnesium hydroxide or other suitable basic compounds, which react with and neutralise part of the excess acid. This raises the pH toward a less acidic level and provides relief. Thus option A is correct; the other options do not describe neutralisation.
