Grades 9–12. In this inquiry-based activity, students learn about pH and the use of red and blue litmus paper, universal pH paper, and common liquid indicators, such as methyl red, bromthymol blue, and phenolphthalein. Students determine the pH of known and unknown acids and bases, measure the pH of various household products, and demonstrate that carbon dioxide in water is acidic.
