Aqueous Standard Reduction Potentials Chemical Sciences Data Tables Aqueous Standard Reduction Potentials Notes to Table Values for 0.1 MPa and 25 o C in aqueous 1.0 molar acid solution, calculated by the undersigned from the tables of molar thermodynamic properties of pure substances and aqueous ions unless the temperature coefficient is followed by an asterisk. In this case the references are given in the Detailed References section below. T , is the temperature coefficient of the isothermal cell in which one of the electrodes is the standard hydrogen electrode.
Ions are all aqueous.
Elements and compounds are pure substances, present in their usual state at 25 o C, unless otherwise indicated.
