LAB: Make a Saturated Solution of Copper Sulfate
(in other words, How much copper sulfate powder can dissolve in 10 mL of water?)
Research Question: How many grams of copper sulfate will dissolve in 10mL of
water? We will answer this by adding a known mass of powder to the water until
no more can dissolve.
Equipment and Materials:





Test tube
Wax film
Test tube rack
Spatula
Measuring cylinder



Electronic balance
Copper sulfate powder
1 L beaker – kept at the teacher desk
Method:
1. Use the measuring cylinder to measure out 10mL of water.
2. Put this water into the test tube.
3. Put the square of paper on the balance and ‘zero’ the balance.
4. Put 3 spatula amounts of copper sulfate onto the piece of paper.
5. Record the mass of the paper with the chemical.
6. Carry the paper carefully to your workstation.
7. Add 2 spatula amounts of copper sulfate to the test tube from the paper.
8. Put the wax film on the test tube and shake the test tube.
9. Add more copper sulfate and shake.
10. Repeat step 9 using smaller amounts until copper sulfate remains undissolved, even after you shake the test tube a lot.
11. Measure the mass of the square of paper with the left over copper sulfate
that was not put into the test tube.
12. Record this mass.
13. Pour the blue crystals of copper sulfate back into the original beaker.
14. Measure the mass of the empty paper.
15. Record this mass.
16. Pour the saturated copper sulfate solution into the beaker at the teacher’s
desk.
17. Clean up your area.
Diagram of the method:
1. On a piece of blank paper, use your pencil and ruler to draw a labeled diagram
of the method.
2. Scan your picture.
3. Paste the scan here.
Hint: FOLLOW SECTION G on the sheet called ‘How to Write a Lab Report’.

The research question was how many grams of copper sulfate could 10mL of
water dissolve?
Before The electronic balance showed 6.00 grams on the scale
During We scooped up spoonfuls of copper sulfate into the beaker and shook
After
We repeated until it couldn’
Conclusion:
1. J1-The research question was how many grams of copper sulfate could
10mL of water dissolve? 10mL of water can dissolve 4.00g of copper
sulfate.
2. J4- Internet shows that 3.2g could be dissolved. The website with this
information is

ve_into_50ml_water_before_reaching_the_saturation_point
Evaluation:
3. 1. Follow K4. Even though you followed the method perfectly, errors
happened because the method was not perfect so you must make a table
to list all the things that make this method not perfect and how you would
improve it.
The weakness in the method
Results could have been affected by
shaking method always changing.
Did not specify what measuring
cylinder to get water with making it
harder to get 10ml.
Water leaked due to fact wax film was
not tightly sealed.
Beaker we used was too small.
How to improve it
Shake beaker in circle every time.
Use 25mL beaker as opposed to 50mL
beaker.
Push down tightly when placing wax
film.
Use a bigger beaker
