Practice Problem 7 Purdue University

REDOX REACTIONS AND ELECTROCHEMICAL CELLS Redox half-cell in relation to a Cu*Cu2+ half-cell will be measured, then, given that the potential of the Cu*Cu2+ half-cell relative to the standard hydrogen half-cell is 0.3402 volts*, the half-cell potential of the other cells will be calculated relative to the standard hydrogen half-cell (2H+ + 2e- > H 2). The standard hydrogen half-cell is

Oxidation-Reduction Reactions Redox

By convention, the electrode written to the left of the salt bridge in this cell notation is always taken to be the anode, and the associated half-equation is always written as an oxidation. The right-hand electrode is therefore always the cathode , and the half-equation is always written as a reduction .
