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 solid sodium bicarbonate and citric acid. When dropped into water, sodium citrate, carbon dioxide, and water are formed: The sodium citrate is a weak base.
