As I was making bath bombs to give for Christmas I felt a little heartburn. I reached for the Alka Seltzer... Wow... $8.99 for 36 tablets! One dose is made of 2 tablets, so that comes to 50 cents per dose. Then I looked at the active ingredients. Citric acid and sodium bicarbonate. Exactly what I was using for the bath bombs!
Alka-Seltzer Science. Alka-Seltzer is made of aspirin, citric acid, and sodium bicarbonate (NaHCO3). When sodium bicarbonate dissolves in water, it splits up to make sodium (Na+) and bicarbonate (HCO3â) ions. The Carbon dioxide is a gas that makes the bubbles you see when you drop the tablets in water.
