A Cell Is Set Up with Copper and Lead Electrodes $\to$

question 45

Multiple Choice

A cell is set up with copper and lead electrodes in contact with CuSO₄(aq) and Pb(NO₃) ₂(aq) ,respectively,at 25°C.The standard reduction potentials are: Pb²⁺ + 2e^- $\to$ Pb $\varepsilon$ ^$\circ$ = -0.13 V
Cu²⁺ + 2e^- $\to$ Cu $\varepsilon$ ^$\circ$ = +0.34 V
If the Pb²⁺ and Cu²⁺ are each 1.0 M,the potential of the cell,in volts,is:

• A)0.47 V
• B)0.92 V
• C)0.22 V
• D)0.58 V
• E)none of these
