Describe how copper can be obtained from solutions of copper compounds by electrolysis. (HT only)

In the subtopic Alternative methods of extracting metals, this learning objective focuses on describe how copper can be obtained from solutions of copper compounds by electrolysis. (HT only). Within Using the Earth's resources and obtaining potable water, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include HT only and electrolysis. Electrolysis means a process that uses electricity to break down compounds into their elements or simpler compounds. Avoid students often confuse electrolysis with other methods of copper extraction, such as displacement or reduction with carbon; instead to fix this, students should focus on the specific process of electrolysis, understanding that it involves using an electric current to separate copper ions from a solution. For exam answers, revise the steps involved in the electrolysis of copper compounds, including the setup and the role of electrodes.
