question 13

Multiple Choice

Consider the following standard reduction potentials. $$\begin{array} { | l | c | } \hline { \text { Reduction Half-Reaction } } & \mathbf { E } ^ { 0 } \text { (volts) } \\\hline \mathrm { Cr } ^ { 3 + } ( a q ) + 3 \mathrm { e } ^ { - } \longrightarrow \mathrm { Cr } ( s ) & - 0.74 \\\hline \mathrm { Cd } ^ { 2 } + ( a q ) + 2 \mathrm { e } ^ { - } \longrightarrow \mathrm { Cd } ( s ) & - 0.40 \\\hline \mathrm { Ni } ^ { 2 + } ( a q ) + 2 \mathrm { e } ^ { - } \longrightarrow \mathrm { Ni } ( s ) & - 0.23 \\\hline\end{array}$$ The Cr/Cr³⁺ half-reaction can be paired with the other two to produce voltaic cells because ________

• A) Cr is a powerful oxidizing agent.
• B) Cr is a powerful reducing agent.
• C) Cr³⁺ is a powerful oxidizing agent.
• D) Cr³⁺ is a powerful reducing agent
• E) Cd and Ni are readily oxidized.
