This is a chemical change, because the carbon dioxide is created from the ingredients when placed in solution. The effervescence is caused when citric acid and sodium bicarbonate combine to form sodium citrate, releasing carbon dioxide gas.

∙ 7y agoThere are too many things going on in that process to characterize it as strictly chemical or strictly physical; a little of both is happening. The most visible evidence of a reaction is actually not the Alka-Seltzer (which is not a single compound) reacting with water at all, it's one component of the Alka-Seltzer reacting with another component of the Alka-Seltzer. The water is just an intermediary.

When you add Alka seltzer to water it gives off carbon dioxide when added to water so it would be a chemical change sense their is a new chemical

If hydrochloric acid is added to sodium hydroxide the temperature increases but there is no visible change did a chemical or physical change occur?
A chemical change occurred. I really hope you did this experiment in a fume hood; adding a strong acid to a strong alkali usually creates a strong explosion.
