First 85 words of the document:

Electrolysis - used to obtain very pure copper
- Means, "splitting up with electricity"
Requires a liquid (electrolyte) which conducts electricity, (electrolyte, is usually free ions
dissolved in water.)
Electrolyte used in purifying copper is Copper (II) sulfate solution.
The electrical supply acts as a pump:
- pulls electron of copper atoms at anode
- offers electrons at cathode
- Impurities dropped at anode as sludge. Pure atoms the bond to the cathode. 2
