The calomel electrode is reversible with repect to :A. `Hg`B. `H^(+)`C

1.	The calomel electrode is reversible with repect to :A. `Hg`B. `H^(+)`C. `Hg^(2+)`D. `Cl^(-)`
Answer» Correct Answer - D Calomel electrode reaction, `1//2Hg_(2)Cl_(2(s))+e^(-)hArr Hg_((l))+Cl_((aq.))^(-)` Calomel electode. `E_(Cl^(-)//Hg_(2)Cl_(2)//Hg)` `E_(Cl^(-)//Hg_(2)Cl_(2)//Hg) + (2.303RT)/(F)log[Cl^(-)]` Thus calomel electrdoe funcations as the reversible chloride electrode.
