Dilutions and Lab

Today in class we completed an aqueous solution lab. We performed this lab to see how the concentrations of the solutions change in a serial dilution. We began the lab with 20 drops of food coloring in 10 mL of water. For the next solution we took 1.0 mL of the previous solution and added it to 9 mL of water. We continued this until the food coloring was no longer visible.

This link has practice problems for serial dilutions, and this website  and second website explains the topic more in depth.
