Which of the following is not a common application of copper?
Copper is found in two types of ore: copper-rich and copper-poor ores. Which of the following is not a common industrial method for removing copper from its ores?
One of the final steps of copper refining is electroplating copper onto a copper electrode. When the deposited copper comes from a copper sulfate solution, such as that produced from sulfuric acid leaching, the process is called electrowinning.
In electrowinning, a lead anode and a copper cathode are immersed in a bath of copper(II) sulfate, and a potential difference is applied.
What is the half-equation of the reaction that occurs at the cathode?
What is the half-equation of the reaction that occurs at the anode?
