Solubility Simulation Lab
Concentration of a solution is a comparison between the amount of ___________________ to the
amount of __________________________. For this lab, the concentration will be measured in
moles per liter, or mol/l. You will be testing various solutes in water to see how concentration can
vary. Go through the following steps and answer the following questions as you run your tests:
1. Put 3 shakes of drink mix into ½ liter of water. What is the concentration
____________________
2. Without adding any more drink mix, add another ½ liter of water. Did the concentration
increase or decrease? Why?
3. Make a prediction of how many shakes it will take for each of the following to reach
maximum concentration in ½ liter of water and what the concentration will be:
Solute
# of shakes
maximum
concentration
Drink Mix
Cobalt Nitrate
Cobalt Chloride
Potassium Dichromate
Potassium Chromate
Nickel Chloride
Copper Sulfate
Potassium Permangranite
4. Test the following solutes for number of shakes and maximum concentration:
Solute
# of shakes
maximum
concentration
Drink Mix
Cobalt Nitrate
Cobalt Chloride
Potassium Dichromate
Potassium Chromate
Nickel Chloride
Copper Sulfate
Potassium Permangranite
5. Does the maximum concentration change if you add more water:
6.
Shake a solute of your choice 5 times into a full liter of water. Record the concentration
_______________________. Now evaporate half of the water. Has the concentration
changed? Why?
