Redox potential of i2

Web1. sep 2024 · The redox potential of the I − /I 3 − couple is not pH-dependent and the redox potential of Zn 2+ /Zn is the difference between acidic and alkaline conditions. In general, the ZnI 2 electrolyte shows slightly acidic condition with pH range of 3–4 and the Zn 2+ /Zn redox pair has a redox potential of -0.76 V (vs. SHE) (Eq. (2)). WebRedox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Some examples of common redox reactions are shown below.
