# Standard Conditions

## 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 = $$\text{1}$$ $$\text{mol.dm^{-3}}$$
