[单选题]
The diagram below show0je x +rc)xwf+6m,bm vs a voltaic cell.3 yp who m6vw/h,d11pk(ulfem cv;,7e The overall reaction taking place in the cell is:v f(6eyhohvkdw ; 1ul 1m/,7pe wm,c3p
$Mg(s)+P{b}^{2+}(aq)\to Pb(s)+M{g}^{2+}(aq)$


Which statement is correct for the magnesium half cell?

A. Magnesium strip is the cathode and is reduced
B. Magnesium strip is the anode and is oxidized
C. Magnesium strip is the cathode and is oxidized
D. Magnesium strip is the anode and is reduced


参考答案:  B


本题详细解析:
Mg(s) loses electrons to prxlpqg qx2*qz:* 1 ct;aoduce $M{g}^{2+}(aq)$.Loss of electrons is oxidation which takes place at the anode.
