$Cu_{(s)}|Cu_{(aq)}^{2 +}||Hg_{(aq)}^{2 +}|Hg_{(l)}$ is

• A. $Hg + Cu^{2 +} \rightarrow Hg^{2 +} + Cu$
• B. $Hg + Cu^{2 +} \rightarrow Cu^{+} + Hg^{+}$
• C. $Cu + Hg \rightarrow CuHg$
• D. $Cu + Hg^{2 +} \rightarrow Cu^{2 +} + Hg$

Answer 1

Answer: (D)

$Cu + Hg^{2 +} \rightarrow Cu^{2 +} + Hg$

Answer 2

Cell reaction: $Cu + Hg^{2 +} \rightarrow Cu^{2 +} + Hg$
