Beer's Law Lab
Flannery Berreth
Background information:
The normal amount of anesthesia used for putting patients under during surgery must be less than 40%. A higher concentration of the solution absorbs more light than a solution of lower concentration.
The direct relationship between absorbency and concentration for a solution is known as Beer's Law.
Scientific Explanations:
Betty would have died in the operation because the mystery solution was 70% anesthesia and the most you could use during an operation is 40%.
Step By Step
1: Set up the colorimeter to the computer and open logger pro.
2: Fill the cuvette 3/4 the way full with distilled water.
3: Put the cuvette in he colorimeter and calibrate it.
4: Empty the cuvette and fill it 3/4 the way full with 20% solution.
5: Put the cuvette in the colorimeter and push the "collect" button and then 'keep." Then type 20% and click enter.
6: Continue this process for all the solutions and then press "stop"
7: After collecting all the data, find the line of best fit.
The mystery solution was last using the same steps listed above.
