The kinetics of the redox reaction between Fe 3+ and I – ion have been reinvestigated over a wide range of reactant concentrations using the method of initial rates. The first-order dependence on Fe 3+ and second-order dependence on I – have been confirmed, the third-order rate constant being 16·0 ± 1·0 I 2 mol –2 s –1 at 25°C and ionic strength of 1·0M.
1998-8-1 · Our data indicate that nitrate reduction is enhanced by low pH and is probably related to iron corrosion. Cheng et al. (1997a)also suggested that iron corrosion is a necessary ingredient for nitrate reduction. Whitman et al. (1924)observed that the iron corrosion rate was pH-insensitive at circum-neutral pH but was greatly enhanced by low pH at pH<4 (at room temperature).

2019-12-19 · I''m a real beginner in chemistry and I''m currently reading about redox reactions. I''m quite confused about this simple redox reaction: Iron (III) ion + Iodide ion ⇌ Iron (II) ion + Iodine. Oxidation numbers + 3 − 1 ⇌ − 1 0 F e 3 + I − ⇌ F e 2 + I 2. I understand the principles of transferring electrons.
2007-4-1 · Only slight extraction of iron(II) is observed (); for a high initial concentration of Fe(II) (80 g/L), about 10 g/L of iron(II) occurs in the organic phase.Unfortunately, iron(II) transfer to the organic phase is higher than in the case of TBP. However, iron(II) extraction seems to be only about 1 g/L when 30 g/L Fe, typical of spent pickling solutions with high zinc(II), is present.
