Beer's Law- What killed Elda?

How to test how much light is going through a beaker

This lab consisted of using different equipment to test how much green food coloring (in this case it represents anesthetic) is in the water. If there was more than 40% of the solvent in the water, then it was too much anesthetic that killed aunt Elda.

For example, we took a cubet with 10% solvent in it and put it in the colorimeter and then a number came out for how much light could pass through. We did this at 10, 15, 20, 30, 40, 50, and 100%. If the cubet representing how much anesthetic Elda had came out over 40%, then that meant it was the anesthetic that killed her. In this case, it did. There was about 70% in Elda's.

History of Anesthesia

People as far back as the Aztecs and Mayans used certain things to try to ease pain. Which is only expected. No one really enjoys being in pain. And when you have to have a procedure, there's a good chance it won't be physically pleasing. So certain herbs were used to try to ease pain during procedures but it wasn't until the 1800's that an actual anesthetic was used. I myself am very grateful to live in a time where those are available. I would prefer, "count back from 10 and when you wake up it'll all be done" rather than "here's a plant to bite on." So thanks to William T. G. Morton for being the first one give that to your patients. I've had five surgeries myself and I'd rather not have had to endure through that experience.
