[单选题]
The diagram below shows a volta 8x3+ee-/ knymery sn8ic cell. The overall reaction t (0mqqh o3t):hwpqrtd;j1 e,,4xql axm yd,w3aking place in the ce 30xrq( xdw;t),hdq p,3ym, aho: 1jqwtqlm e 4ll is:
$Mg(s) + Pb^{2+}(aq) \rightarrow Pb(s) + Mg^{2+}(aq)$
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 prod*m x tupvg2p8h- rz4d;uce $Mg^{2+}(aq)$.Loss of electrons is oxidation which takes place at the anode.
