Pre-Lab knowledge requsits
-What a colorimeter is and how we set it up, hwo we use it, and safety protocols
-How a colorimeter works which is it shoots light through the solution and test the concentration and absorbance and gives us the number which we add to our graph
How do you make a solution?
First get the base measurement of plain waterThen you figure out the percentage of Green and water you will need
Fill a cuvette with one of the green solutions
Measure both percentages into the same cuvette
Cap the cuvette
Put cuvette in colorimeter
Record the number given by the colorimeter
Add number to graph
When a new number is added the graph automatically updates for you
For example if you want a 20% solution and you have a 10 milliliter cuvette, you would put 8 milliliters of water in the cuvette and you would add 2 milliliters to the cuvette, then you would put it in the colorimeter find the concentration and absorbance and record them and move on.
