Extract

As I, did not complete part C myself, but received limited notes from a friend I can only assume that Sodium Chloride/ Copper Chloride (NaCl/CuCl^2) does not dissolve well in the substance ethanol, where as the mixture of 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.
