In this lab experience, students explore the effect of carbon dioxide dissolution on the pH of a saline solution that resembles seawater and be able to correlate the increased uptake of carbon dioxide and the acidification of surface ocean waters. Students will observe that the dissolution of carbon dioxide gas into a saline solution that resembles seawater causes a decrease in the pH of the solution. This change in pH will be measured directly with a pH meter. Also, the change in pH will cause the change in color of the solution due to the presence of an acid–base indicator.
