Why do Alka Seltzer tablets fizz in water?

Why does Alka-Seltzer explode in water?

Alka-Seltzer tablets contain citric acid and sodium bicarbonate – a base. (And aspirin.) When you drop the tablet in water, the acid and base mix and react, forming carbon dioxide gas which bubbles up to the surface of the water.

As an Alka-Seltzer tablet dissolves in water, it liberates carbon dioxide. The carbon dioxide dissolves in the water and then comes out of solution as a gas. This carbon dioxide gas has mass, but since it is a gas it escapes from the container and diffuses into the atmosphere.

Why is aspirin slightly soluble in water?

Solubility. Aspirin is only slightly soluble in water and acidic solutions such as is present in the stomach. Aspirin contains polar functional groups which can form hydrogen bonds with polar water molecules.
