many antacids contain solid calcium carbonate. explain how antacids with calcium carbonate function.
Answer
Answer:
Calcium carbonate in antacids reacts with excess stomach - acid (hydrochloric acid) to neutralize it. The chemical reaction is $CaCO_{3}+2HCl = CaCl_{2}+H_{2}O + CO_{2}\uparrow$. This reduces the acidity in the stomach, relieving heartburn and indigestion.
Brief Explanations:
Antacids work by neutralizing acid. Calcium carbonate is a base that reacts with stomach - acid (HCl) in a neutralization reaction. The products are calcium chloride, water, and carbon dioxide gas. This lowers stomach acidity.
