Next, ask students to determine which cup represents 1 part per million (ppm), and how many more cups would be required to represent 1 part per billion (ppb). Have students determine the concentration of each cup in terms of (volume of solute) / (total volume).Note when you can first discern the sweet taste of the solution in the cup. Beginning with cup F, taste-test each solution by sipping a small amount of liquid from each cup.
