SHE
Standard Hydrogen Electrode: The reference point ($0\text{V}$) for measuring electrode potentials.
Cell Potential ($E^ø_{cell}$)
The voltage difference between two half-cells in an electrochemical cell.
Faraday Constant ($F$)

Selective Discharge
The preference of one ion to be oxidized or reduced over another in electrolysis.
Electroplating
The use of electrolysis to coat a conductive object with a thin layer of metal.
