Subjecting water to a high dosage of? Radiation produces significant amounts of aquatic electrons which are able of reducing transition metal ions.
If an acidic solution of a first row transition metal complex, [MCl6]n- exhibits 3 d-d transitions at 12040, 24080 and 25800 cm-1 in the UV/vis spectrum. Upon irradiation with? Rays, a color change is observed, as well as the UV/vis spectrum now displays three new bands at 8000, 13200 and 22920 cm-1 with the preceding three absorption bands completely absent.
Upon exposing this solution to the air the original spectrum is regenerated, throughout an oxidation reaction involving O2.
1) Develop a balanced chemical equation for the oxidation reaction. This will comprise identifying plausible half-reactions and summing them together.
given that, for H2C2O4(aq), Ka1 = 6.5 x 10-2 and Ka2 = 6.1 x 10-5. Don't forget that Kw = 1 x 10-14.
