The diagram below shows yv9nf p)vi 6 qpgb.i +8q6kay9a v j0jzti*) d zk,oltaic cell. The overall reaction taking place in the z, jd kt)*0izj cell 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 prgh;uwlja 59g07,minq g5 z9cg6av6lahf .c,n oduce $Mg^{2+}(aq)$.Loss of electrons is oxidation which takes place at the anode.
