Question

Electrochemical Measurement of Concentration

An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode.

What is the potential of this cell at 25°C if the copper electrode is placed in a solution in which [Cu²⁺] = 9.2×10^-5 M?

The copper electrode of the above cell is placed in a solution of unknown [Cu²⁺]. The measured potential at 25°C is 0.160 V. What is [Cu²⁺] (in mol/L)? (Assume Cu²⁺ is reduced.)

A calibration curve to show how the cell potential varies with [Cu²⁺] may be constructed. A plot of cell potential (in V, with the same sense as in question 1) versus log₁₀[Cu²⁺] should yield a straight line. What is the slope of this line?
