I look forward to the day when you can safely visit my office! This is a photograph of the GIANT painting that I made for my office that I mentioned in our last lecture.

In this lecture you will learn about Beer's Law and the correlation between absorbance and concentration. Electrolytes, acids, and bases will also be introduced. We will finish up with learning how to use molecular formulas to write full ionic and net ionic equations.

The materials for this lecture are:

Chapter 4 slides (slides 11, 13-22)

Practice problems worksheet

Lecture 13 - Attendance/Comprehension Quiz

Introduction and Beer's Law

For an interactive demonstration of Beer's Law check out this link. You can change the path length and concentration to see what effect that has on absorbance. Hit the red button above the word "wavelength" to measure the absorbance.
