Standard conditions

Standard electrode potentials are a measurement of equilibrium potentials. The position of this equilibrium can change if you change some of the conditions (e.g. concentration, temperature). It is therefore important that standard conditions be used:

  • pressure = \(\text{101.3}\) \(\text{kPa}\) (\(\text{1}\) \(\text{atm}\))

  • temperature = \(\text{298}\) \(\text{K}\) (\(\text{25}\) \(\text{℃}\))

  • concentration = \(\text{1}\) \(\text{mol.dm$^{-3}$}\)
