What is produced when acetic acid interacts with calcium carbonate?

1. Calcium acetate
2. Calcium acetate and carbon dioxide
3. Calcium acetate, carbon dioxide, and water
4. Calcium acetate and water

Correct answer: Calcium acetate and carbon dioxide

Solution

When acetic acid (CH3COOH) reacts with calcium carbonate (CaCO3), it produces calcium acetate (CH3COO—Ca), carbon dioxide (CO2), and water (H2O). This is a typical acid-carbonate reaction.
