The diagram below shows a voltaic cell. The idy4:7ld c 6lac2x80vk (u lsh overall reaction taking +3 a;wv uuh;xzq,kb9:fkj jt-place in the cell is: ;ux wha;-9: ,b3u +jjkfzt qkv
$Mg(s) + Pb^{2+}(aq) \rightarrow Pb(s) + Mg^{2+}(aq)$
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 prjrkbrc*; 2d) fxq;yz6 oduce $Mg^{2+}(aq)$.Loss of electrons is oxidation which takes place at the anode.
