• B. Acidic
• C. Neutral
• D. All the above

Answer 1

The Correct Option is A

To solve the problem, we need to understand the nature of the chemical used in antacids.

1. Understanding Antacids:
Antacids are substances used to neutralize excess stomach acid. They are usually basic in nature and help to raise the pH level of the stomach to relieve acidity and heartburn.

2. Common Chemicals in Antacids:
Antacids contain basic (alkaline) substances like sodium bicarbonate (NaHCO₃), calcium carbonate (CaCO₃), or magnesium hydroxide (Mg(OH)₂), which react with hydrochloric acid (HCl) in the stomach to form water and neutral salts.

3. Evaluating the Options:
- Option (A): Basic – Correct, as antacids are basic substances.
- Option (B): Acidic – Incorrect, as antacids are not acidic.
- Option (C): Neutral – Incorrect, as antacids do not have a neutral pH; they are basic.
- Option (D): All the above – Incorrect, as only basic chemicals are used in antacids.

Final Answer:
The correct answer is option (A): Basic.
