Scenario 1: Adding more water to the mixture
Concentration of dilute Drink mix mixture: decreases
Concentration of pure Drink mix solution: stays the same
Scenario 2: Adding more Drink mix to the mixture
Concentration of dilute Drink mix mixture: increases
Concentration of pure Drink mix solution: increases
Scenario 3: Stirring the mixture
Concentration of dilute Drink mix mixture: stays the same
Concentration of pure Drink mix solution: stays the same
Scenario 4: Allowing the mixture to sit undisturbed
Concentration of dilute Drink mix mixture: stays the same
Concentration of pure Drink mix solution: stays the same
Use the PhET simulation to identify what happens to the concentrations of a dilute Drink mix mixture or a pure Drink mix solution for the following scenarios. A pure Drink mix solution can be obtained by draining all the mixture, then adding Drink mix to the container as a Solution (radio button in the upper right area of the simulation). Note that the Concentration meter can be placed toward the bottom of the container or in the stream of the Drink mix. Drag the appropriate items to their respective bins.
