A voltaic cell designed to measure [Cu2+]is constructed of a standard hydrogen electrode and a copper metal electrode in the Cu2+ solution of interest.

1. If you wanted to construct a calibration curve for how the cell potential varies with the concentration of copper(II), what would you plot in order to obtain a straight line?
Answer: log[Cu2+]versus E0cell.

2. What would be the slope of the line? Express your answer using two significant figures.

Answer: ? V
