Calcium Carbonate and Hydrochloric Acid (Antacid)

CaCO3 + 2HCl → CaCl2 + H2O + CO2

개요

Calcium carbonate, found in Tums antacid tablets, neutralizes hydrochloric acid in the stomach to form calcium chloride, water, and carbon dioxide gas. The carbonate ion acts as a base, accepting protons from HCl. The CO₂ evolved can cause belching.
