Several titrations can be performed during one class period with surprisingly good results. Students determine the percentage of acetic acid in household vinegar by titrating the vinegar with a sodium hydroxide solution of known concentration. The indicator phenolphthalein will produce a pink endpoint. Instructions include step-by-step explanations of the calculations. All chemicals and specialized equipment are included.
Complete for 30 students working in pairs. Fifteen reusable 24-well plates are recommended and available separately.
