Abstract
Drug stores, bath and body stores, and sites on the World Wide Web promote the use of bath bubblers or bath bombs for a refreshing and fragrant bath. Drop one into bath water and watch it fizz, whirl and spin! These solid molded shapes are expensive to buy in stores, but easy to make with materials found in the home. A chemical reaction occurs when the bath bubbler comes in contact with water. This reaction involves the citric acid (H3C6H5O7, a triprotic weak acid) and baking soda (NaHCO3) found in a bath bubbler. The water dissolves the solid bubbler and initiates the reaction of citric acid with baking soda. Carbon dioxide fizzes out of the bubbler. In this Activity, students make several bubblers and examine their properties in both cold and hot water.
