Stabilization and strong oxidizing properties of Ag(II) in a fluorine-free solvent

Divalent silver is stabilized in concentrated sulphuric acid and oleums. The formal redox potential of the Ag(II)/Ag(I) redox pair is markedly dependent on the Hammett acidity function and it reaches +2.90 V vs. NHE in 33% oleum thus rivalling E° for the F2/2F(-) redox pair (+2.87 V).
