Background Information

Anesthesia is defined as a freedom from pain, it is most often used in medical treatments. The desirable things anesthesia dose are it makes you feel no pain, the undesireable things it does is there is a chance you could die from using anesthesia. In this lab we are testing to see what percentages of anesthesia doctors were using on a made up person because when anesthesia is used if the percentage given is over 40 then there is a chance that person could die. To do this we are using a colorimeter. We also used Beers law in this experiment to find the absorption of the solutions. This is when we used the colorimeter, we plugged in the concentration we were told it was and then the calorimeter would give the concentration percentage number and these ordered pairs gave us something close to a line.

Aunt Betty is getting her anesthesia in the picture above.


I our experiment when we tested to see the percentages of anesthesia used we found that it was %70 which is %30 higher than the minimum. So in this procedure Betty, the patient, would've died because the concentration was too high. In some rare cases people die on the operating bed but most deaths are from complications in health from the experiment

This is the final result of the experiment using beers law. To find this you plug in the absorption.

How to make a percent solution

  1. Change the percent solution to a decimal so if its 50% it would be .5.
  2. Next you need to multiply this by the total volume.
  3. The third step is to subtract the volume of your solute from the volume.
  4. Finally you would subtract your solute volume from your solution volume and add however much water that would be.
