Comparison of the Effects of Increased CO2 in the Air to Seawater and Distilled Water

Type of Resource



This well-designed experiment compares CO2 impacts on salt water and fresh water. In a short demonstration, students examine how distilled water (i.e., pure water without any dissolved ions or compounds) and seawater are affected differently by increasing carbon dioxide in the air.
