Which statement about8;c5xux;ka .uda1 xu*5a znmnpb 1ty7cd 5e(gdwj*en/c;o, b0 qecgy*e*gqj985yuu electroplating an object with silver is incorrect?
A. The object is placed at the negative electrode
B. Electrons travel from the positive electrode to the negative electrode
C. The silver electrode must be pure
D. The anode consists of silver metal
参考答案: C
本题详细解析:
In electroplating, the anode is made of silver metal, which i49.c ckxzb /jn,/ ol/p64qn aowh:vris oxidized to $Ag^+$ ions. The $Ag^+$ ions are then reduced at the cathode to Ag metal, resulting in a coating around this object.
Any impurities will sink to the bottom of the vessel.
In electrolytic cells, the anode is positive, and the cathode is negative. As a result, electrons travel from positive to negative.
