- Watch glass.
- Glass rod.
- 100mL Beaker (2)
- 25mL graduated cylinder.

…showed last 75 words of 580 total…sodium Chloride/ Charcoal did not fully dissolve in water. I believe that the combination of Sodium Chloride/ Copper Chloride and ethanol were unsuccessful because of ethanol's high alcohol content as it did dissolve in water effectively. When the two substances were separated it left crystals which where white in colour.
Conclusion
In Conclusion the overall experiment was a success. My group was successfully able to separate the before mentioned substances after mixing and/or heating.
