Question
What is occurring at the cathode of the electrochemical cell containing the reaction represented by the following equation?Zn + Cu2+ → Cu + Zn2+Question 10Select one:a.oxidation of zincb.copper gains electronsc.copper loses electronsd.oxidation of copper
Solution
In an electrochemical cell, the cathode is the site of reduction. Looking at the given reaction, Zn is being oxidized to Zn2+ (it's losing electrons), while Cu2+ is being reduced to Cu (it's gaining electrons). Therefore, at the cathode of this electrochemical cell, the process that is occurring is: copper gains electrons. So, the correct answer is b. copper gains electrons.
