What happens to alka seltzer when put in orange juice?

Alka-Seltzer is an effervescent tablet that contains aspirin, sodium bicarbonate, and citric acid. When Alka-Seltzer is dropped into orange juice, the citric acid in the juice reacts with the sodium bicarbonate in the tablet to produce carbon dioxide gas. This gas causes the tablet to fizz and dissolve. The aspirin and sodium bicarbonate then dissolve in the juice and can be absorbed by the body.

The reaction between Alka-Seltzer and orange juice can be represented by the following equation:

NaHCO3 + C6H8O7 → CO2 + H2O + C6H5O7Na

This reaction is an example of an acid-base reaction. In this type of reaction, an acid and a base react to form water and a salt. In the case of Alka-Seltzer and orange juice, the citric acid is the acid and the sodium bicarbonate is the base. The carbon dioxide gas that is produced is a by-product of the reaction.

The reaction between Alka-Seltzer and orange juice is a common example of a chemical reaction that occurs in everyday life. This reaction can be used to explain the fizzing of other effervescent tablets, such as those used for indigestion or to add flavor to drinks.
