The galvanic cell with the cell reaction
Mg(s) + 2Ag+ (0.001M) → Mg2+ (0.65M) + 2Ag(s)
is correctly represented as
1
\(\mathrm{Mg}^{2+}(0.65 \mathrm{M})\left|\mathrm{Mg} \| \mathrm{Ag}^{+}(0.001 \mathrm{M})\right| \mathrm{Ag}\)
2
\(\mathrm{Mg}\left|\mathrm{Mg}^{2+}(0.65 \mathrm{M}) \| \mathrm{Ag}\right| \mathrm{Ag}^{+}(0.001 \mathrm{M})\)
3
\(\mathrm{Mg}^{2+}(0.65 \mathrm{M})|\mathrm{Mg} \| \mathrm{Ag}| \mathrm{Ag}^{+}(0.001 \mathrm{M})\)
4
\(\mathrm{Mg}\left|\mathrm{Mg}^{2+}(0.65 \mathrm{M}) \| \mathrm{Ag}^{+}(0.001 \mathrm{M})\right| \mathrm{Ag}\)
