Action What happens to concentration? Drink mix is added 1 Water Is added Evaporation Solution occurs Is drained Remove Solute Solute is removed
1. Open the PhET Concentration Simulation1 on the PhET website (https://phet.colorado.edu/sims/html/concentration/latest/concentration_en.html)
2. Move the concentration sensor into the solution. Add a couple shakes of drink mix to the
water. Then take a couple minutes to see how the moving parts work and affect the concentration of
the solution. Fill in the table below.
3. Click “Remove Solute”. Change the solute to “Drink mix” and add as much as you can.
4. How do you know when a solution is saturated?
5. When a solution is saturated and additional solid solute is added, what happens?
6. Why do you think this is?
7. How does adding this additional solute change the concentration of this saturated solution?
8. How does evaporation change the concentration of a saturated solution?
