MCQ
Which of the following is an antacid?
  • A
    $\mathrm{Mg}(\mathrm{OH})_2$
  • B
    $\mathrm{Al}(\mathrm{OH})_3 \mathrm{gel}$
  • C
    $\mathrm{MgCO}_3$
  • ✓
    All of the above
✓

Answer

Correct option: D.
All of the above
All are antacids, as all these have a strong affinity for hydronium $\left(\mathrm{H}_3 \mathrm{O}^{+}\right)$ ion in their solutions, hence neutralising the effects of gastric acids in the stomach.
