"Good to the Last Drop" Lab

Yesterday in class, we completed a lab having to do with finding the concentration of different dilutions using molarity and volume.

We started out with 10mL of water in a cup and then added red food dye to it. Then we took 1mL of that solution and put it in a new cup, filled with 9mL of un-colored water. We then repeated this 3 more times. Here is what the set-up of the lab looked like:

Each time we moved 1mL of the old dilution to a new cup with water, the dilution became clearer and clearer, creating a cool ombre effect. Here is what all the cups of water looked like after we were done:

Here is a helpful website that I found to help with calculating concentrations and also explaining what dilutions are: Dilutions
