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 work station.
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’.

Qualitative data for Copper Sulfate dissolve in water
Before
The water is transparent. Lots of copper sulfate is on the
electronic balance.
Put the some of copper sulfate in the cylinder and then
the Copper Sulfate dissolved and water changed by sky
blue.
More than half of copper sulfate added in the water, the
copper sulfate don’t dissolved. The color was blue.
(not sky blue)
During
After
Conclusion:
1. J1 - 3g of the Copper Sulfate dissolve in the 10ml of water.
2. J4 – In internet it says 2.03g of copper sulfate can dissolved in the
water.

Evaluation:
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.
How To Do Better Science Lab?
The weakness in the method
Poured too much Copper Sulfate on the
Table
How to improve it
Put the Copper Sulfate more careful
Too hard shaking so the water leak little
bit
Try to shake more slowly and wrap the
wax paper more hard.
