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 tablets contain two acids, aspirin and citric acid. Baking powder may contain an acid like cream of tartar, calcium acid phosphate, or some other acid. When either of these products is placed in water, the acid and sodium bicarbonate react to produce carbon dioxide gas.
