Which of the following are used as an antacid to reduce acidity in stomach?
Which of the following are used as an antacid to reduce acidity in stomach?
- A. Sodium carbonate and magnesium hydroxide
- B. Magnesium hydroxide and sodium hydroxide
- C. Sodium bicarbonate and calcium hydroxide
- D. Sodium bicarbonate and magnesium hydroxide
Step-by-step solution
Antacids are weak bases that neutralize stomach acid. Common antacids include magnesium hydroxide (Mg(OH)2) and sodium bicarbonate (NaHCO3). Sodium hydroxide (NaOH) and calcium hydroxide (Ca(OH)2) are strong bases and too caustic for use. Sodium carbonate (Na2CO3) is used in some antacids but can produce excessive gas and is less common. Therefore, the combination of sodium bicarbonate and magnesium hydroxide is most appropriate.
