The Nernst equation is a fundamental equation in electrochemistry that relates the electrode potential, often denoted as E, to the concentrations of the electroactive species involved in a half-cell reaction. In the case of the reduction of dichromate ions (Cr2O7^2-) to trivalent chromium ions (Cr^3+) in acidic conditions, the half-cell reaction is as follows:
Cr2O7^2- + 14H^+ + 6e^- -> 2Cr^3+ + 7H2O
The Nernst equation can be deduced for this half-cell reaction as follows:
E = E° - (0.0592/n) * log(Q)
Where:
E is the cell potential under non-standard conditions.
E° is the standard cell potential under
