Question

Quizplus · Accepted Answer

Silver ions are reduced, as they gain electrons and are converted into solid silver during plating. However, they are the oxidizing agent, as they cause copper to be oxidized and lose electrons, enabling the reduction of the silver ions. Therefore, choice C is the correct answer.
