Towers of the Lost City

Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the buffering ability of sea water. They apply the results to the waters around the Lost City hydrothermal vents.
