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

question 17

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
$\varepsilon$ ° = -0.13 V
Cu²⁺ + 2e^- $\to$ Cu
$\varepsilon$ ° = +0.34 V
If sulfuric acid is added to the Pb(NO₃) ₂ solution,forming a precipitate of PbSO₄,the cell potential:

• A)increases
• B)decreases
• C)is unchanged
• D)can't tell what will happen
• E)none of these
