This video demonstrates how to determine the concentration of an unknown base by titration. Proper use of graduated cylinders for volume measurement and use of a burette for titration using the pH indicator phenolphthalein are shown. Calculations to determine concentration of the unknown are shown using the m1v1 = m2v2 formula. This activity is included in the laboratory textbook Biotechnology: A Laboratory Skills Course.
