The two main types of bases used in antacids are carbonates and hydroxides. These are weak bases that serve to neutralize the acidity of the stomach.
Examples of common antacid bases include aluminum hydroxide, magnesium carbonate and sodium bicarbonate, magnesium hydroxide, calcium carbonate and potassium bicarbonate.
Hence, the correct option is (c).

Introduction:
The base used as an antacid is Magnesium hydroxide. Antacids are used to neutralize excess stomach acid and provide relief from heartburn, acid indigestion, and upset stomach. Magnesium hydroxide is one of the commonly used bases in antacid preparations due to its properties and effectiveness in reducing gastric acidity.
Explanation:
Magnesium hydroxide:
- Magnesium hydroxide (Mg(OH)2) is an inorganic compound that is commonly used as an antacid. It is a white solid with low solubility in water.
- When consumed, magnesium hydroxide reacts with the hydrochloric acid in the stomach to form magnesium chloride and water, thereby neutralizing the excess acid.
- The chemical equation for the reaction is as follows: Mg(OH)2 + 2HCl → MgCl2 + 2H2O
- The resulting products, magnesium chloride and water, are harmless and can be easily eliminated from the body.
Properties of Magnesium hydroxide as an antacid:
- Magnesium hydroxide has a high neutralizing capacity, meaning it can effectively neutralize a large amount of acid in the stomach.
- It has a relatively low solubility, which ensures that it does not dissolve quickly and provides a longer-lasting effect.
- Magnesium hydroxide also acts as a laxative, promoting bowel movements and relieving constipation, which is a common side effect of antacid use.
Comparison with other options:
- Calcium hydroxide (Option A) is another base that can be used as an antacid. However, it is less commonly used compared to magnesium hydroxide.
- Barium hydroxide (Option B) is not used as an antacid. It is a toxic compound and can cause serious health issues if ingested.
- Silver hydroxide (Option D) is also not used as an antacid. It is a relatively unstable compound and has limited applications in medicine.
Conclusion:
In conclusion, the base used as an antacid is Magnesium hydroxide (Option C). It effectively neutralizes excess stomach acid, has a longer-lasting effect, and provides relief from heartburn and indigestion. It is a safe and commonly used compound in antacid preparations.
