Students engage in three experiments to investigate the properties of acids, bases, and salts. First they explore the pH of acids and bases using five different indicator solutions. Learn how to choose an appropriate indicator to determine the endpoint of an acid base reaction. Then they explore the four classic scenarios for acid base titration reactions to distinguish strong and weak acids and bases. Titration curves are plotted to derive equivalence points for each scenario. Finally, students apply the techniques learned in a quantitative titration to determine the concentration of acetic acid in household vinegar by titrating the weak acid with a strong base in the presence of phenolphthalein. Includes all necessary chemicals and micro supplies for investigations. Requires distilled water, but not included. Designed for 24 students working in groups of four. Allow three lab periods.
