Complete the description of the standard electrochemical reference points.
The ______ constant is the charge carried by one mole of electrons, the standard ______ electrode is defined as exactly zero volts, and the ______ equation gives the cell potential away from standard conditions.
Word bank: Faraday · hydrogen · Nernst · Clausius
Hints
- One is a constant, one a reference half-cell, one an equation.
- Clausius belongs to thermodynamics, not electrochemistry.
Show the answer
The Faraday constant is the charge carried by one mole of electrons, the standard hydrogen electrode is defined as exactly zero volts, and the Nernst equation gives the cell potential away from standard conditions.
The Faraday constant converts moles of electrons into coulombs, the standard hydrogen electrode fixes the zero of the potential scale so every other potential is a comparison against it, and the Nernst equation handles non-standard concentrations.
