Final answer:
The process of refining copper by electrolysis of blister copper involves casting impure copper into large plates, using them as anodes in an electrolyte solution, and passing an electric current to produce pure copper metal.
Step-by-step explanation:
The process of refining copper by electrolysis of blister copper involves several steps. First, the impure copper called blister copper is cast into large plates which are used as anodes. Then, the anodes are placed in an electrolyte solution containing copper(II) sulfate. When an electric current is passed through the solution, copper ions from the anode gain electrons at the cathode and form pure copper metal. This process helps to remove impurities and produce high-quality copper.
