摘要: Oxidation of titanium(III) to titanium(IV) by hydroxyl radicals is observed on pulse radiolysis solutions at pH 1·4 in the absence formic acid. In presence 1·0M-formic acid formate radical CO2H (pKa= 1·4) produced first, and subsequently reduced titanium(II), k=ca. 5 × 106 l mol–1 s–1 room temperature, 1·4. Under same conditions this also reduces europium(III), but not ytterbium(III), chromium(III), or scandium(III), Reduction scandium(III) 4·2–4·9
