carbonic acid

Answer 1

The item that is a salt among the options you provided is **calcium carbonate**.

Here’s a brief explanation of each option:
- **Antacid**: This is a term for a group of substances that can neutralize stomach acidity, and it often contains various compounds, some of which can be salts, but it is not specifically a salt itself.
- **Calcium carbonate**: This is a salt that is formed from the reaction of calcium (a base) with carbonic acid (an acid). It is often used in antacids and as a dietary calcium supplement.
- **Sodium hydroxide**: This is a strong base (not a salt) and is typically used in various industrial applications and cleaning agents.
- **Carbonic acid**: This is an acid (H2CO3) and is not a salt.

Thus, the correct answer is **calcium carbonate**.
