Effervescent tablets dissolve in water and release carbon dioxide.

Explanation:
Effervescence arises when a solid dissolves in water and a gas is produced. Effervescent tablets are designed with an acid and a carbonate source; when they contact water, the acid-base reaction releases carbon dioxide gas. The dissolved components allow the reaction to proceed rapidly, and the CO2 forms bubbles that escape, giving the characteristic fizz. This is the intended behavior of such tablets, so the statement is true. While storage or water temperature can influence how quickly the fizz appears, the fundamental property remains that these tablets dissolve in water and release carbon dioxide.
