Milk of magnesia is useful for what purpose?

Answer and explanation

Correct answer: Reducing acidity (अम्लता कम करने में)

Milk of magnesia is a suspension of magnesium hydroxide, Mg(OH)₂, which is a weak base. The governing concept is neutralisation: magnesium hydroxide reacts with excess hydrochloric acid in the stomach and reduces its acidity, so it works as an antacid. Therefore option A is correct. Rusting iron, acidifying water and producing litmus are unrelated to the normal function of milk of magnesia.
