[单选题]
The diagram below shows a v x il g1nd)0 s* l,30vlgp/dwimq8y qo9oltaic cell. The overall reaction ta kg/(h,bm 1- jbz(8wji qjvev v 54gwf6king place in the cell vf , jzb4w6q v8/vb jiegj(mw(5-hkg1 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 produce id9g 5 c6h7tsbn)nem vt;9tz4 $Mg^{2+}(aq)$.Loss of electrons is oxidation which takes place at the anode.
