question 9

Multiple Choice

The standard oxidation potential, $E_{o x}^{\circ}$ ,of Cu(s) is ?0.339 V.The oxidation product is the copper(II) ion.Write the equation for the standard reduction potential.What is the value of the standard reduction potential, ${E}_{\text {red }}^{0}$ ?

• A) Cu²⁺(aq)? Cu(s)+ 2e? \({E}_{\text {red }}^{0}\) = ?0.339 V
• B) Cu²⁺(aq)+ 2e? ? Cu(s) \({E}_{\text {red }}^{0}\) = +0.339 V
• C) Cu(s)+ 2e? ? Cu²⁺(aq) \({E}_{\text {red }}^{0}\) = ?0.339 V
• D) Cu(s)? Cu²⁺(aq)+ 2e? \({E}_{\text {red }}^{0}\) = +0.339 V
• E) Cu(s)+ 2e? ? Cu²⁺(aq) \({E}_{\text {red }}^{0}\) = +0.339 V
