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!
Composition[edit] Alka-Seltzer contains three active ingredients; aspirin (acetylsalicylic acid) (ASA), sodium bicarbonate, and anhydrous citric acid. The aspirin is a pain reliever and anti-inflammatory, and the sodium hydrogen carbonate and citric acid form an antacid by their effervescent reaction with water.
