Beer's Law Lab
Kelsey Phelps Period 2
1- An experience that you have had with anesthesial (dentist/doctor/???) If you have never had the experience, do you foresee a future experience? I have had laughing gas at the dentist because I have high anxiety and don't trust the dentist. When I'm on it I kind of feel numb and I am a care free person.
2- What are characteristics (functions ) of an anesthesia that are desirable? It will cause you to not feel pain, you will lose a sense of consciousness , and a sense of numbness.
3- What are characteristics (functions) of an anesthesia that are not desirable (dangerous)? It is very toxic and flamable. It could cause an explosion during the surgery and it can cause the lungs to collapse. overall a dangerous tool.
In order to complete this lab you need to know some basic definitions such as:
-Anesthesia: a general loss of the senses of feeling, as pain, heat , cold , touch and other less common varieties of sensation.
-Absorbance: the capacity of a substance to absorb radiation, expressed as the common logarithm of the reciprocal of the transmittance of the substance.
- Anesthesia solution
- Graduated Cylinder
This is where you will fill your percent solutions about 3/4 full each time.
This is the tool you will hook up to the computer to collect the data. You will place each cuvette, one at a time, and test it.
The tube looking thing inside the glass is a very use-full tool to place each solution into the cuvette.
How to make a solution
- With the percentage given, fill that amount with water.
Ex: Given 30%, fill the beaker with 3 mL of water.
- Subtract that number from 10 to receive the amount of solution needed.
Ex: 10 - 3 = 7 mL of solution
Now you have your anesthetic solution.
Fill the cylinder with the specified amount of water.
Fill the remaining space in the cylinder with your solution.
Once your solution is complete, pour it into a beaker.
First make sure you have the colorimeter set up on the computer and open up logger pro which is the program that is used to collect the data. Secondly, fill each cuvette 3/4 with each different solution. Everytime you place the cuvette into the colorimeter, make sure you hold it by the rigged side not the clear side. On the first test, click caliborate and than click keep. Every other solution from now on, you only have to click keep every time. After the last solution, click stop.
1-Was the concentration of Aunt Elda's anesthesia too strong? (how do you know) No it was below 40%.
2- do you have a hypothesis for the cause of her death? The anesthesia did not kill her, it must have been something to do with the surgery.
3- How did Beer's Law help you solve this case? Because we had the solution that was used for her and the tools and other examples to compare it to, to guesstimate what percentage it could have been was fairly easy.
