Question

Give an example of an antacid.

Hint:

Antacids perform a neutralization reaction: Acid + Base \(\rightarrow\) Salt + Water.

Answer 1

Step 1: Understanding the Concept:
Antacids are mild bases that are used to neutralize excess stomach acid (Hydrochloric acid) during indigestion or heartburn.

Step 2: Detailed Explanation:
Since they must be safe for human consumption, weak bases are used.
Common examples include:
1. Magnesium hydroxide (\(\text{Mg}(\text{OH})_2\)), commonly known as Milk of Magnesia.
2. Sodium bicarbonate (\(\text{NaHCO}_3\)), commonly known as baking soda.
3. Aluminum hydroxide (\(\text{Al}(\text{OH})_3\)).
Providing any one of these is sufficient.

Step 3: Final Answer:
Magnesium hydroxide is a common antacid.
