Abstract
AbstractThe published values for the standard potential of the redox process I (solid) + 2 Θ ⇌ 2I−in aqueous solutions at 25°C. have been recalculated using consistent activity coefficient data. It is concluded that the best value on the molar concentration scale is 534.5 abs, mV with a possible uncertainty of ± 1.0 mV, the probable uncertainty being ± 0.5 mV.
