[单选题]
The diagram below shows p+bd7y- p qi-q -jz(.vusdjr/a Dd nripr d.bwo(3qg8 8.aniel cell. Zinc is more reactive than copper. When the celri( grnd 8 8pow..qd3bl is operating, which statement about the ions in the cell is correct?

A. Positive ions in the salt bridge diffuse into the copper half cell
B. Positive ions in the salt bridge diffuse into the zinc half cell
C. $Zn^{2+}(aq)$ ions are deposited at the zinc electrode as Zn(s)
D. he concentration of $Cu^{2+}(aq)$ ions increases in the copper half cell


参考答案:  A


本题详细解析:
The positive ions (cations) move in the direction of h5pkwka03t c/7d.b vy the cathode as the positive .57 dpk/wkbhac30 yvt$Cu^{2+}$ ions are used up. Zn being more reactive than copper, Zn(s) is the anode where oxidation occurs, and Cu(s) is the cathode where reduction of $Cu^{2+}(aq)$ occurs.
