5.111 Principles of Chemical Science

5.111 Principles of Chemical Science (Fall 2014, MIT OCW). Instructor: Professor Catherine Drennan. This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. One year of high school chemistry is the expected background for this freshman-level course.

Lecture 23 - Acid-Base Titrations Part I. A common chemistry laboratory experiment involves titrating a strong base into a weak acid, drop by drop, until a color change of an indicator dye tells the student that the equivalence point has been reached. By determining the volume of strong based needed to reach the equivalence point, the molecular weight and/or pK_a of the weak acid can be determined. In this lecture, we start to work through the calculations underlying acid-base titrations. (from ocw.mit.edu)
