WebThe reaction of iron (III) with thiosulfate produces a deep violet complex anion, Fe (S 2 O 3) 2–. This decomposes slowly with the fading of the violet colour: Fe (S 2 O 3) 2— (aq) + Fe 3+ (aq) → 2Fe 2+ (aq) + S 4 O 62– (aq) The presence of copper (II) ions catalyses the decomposition reaction, and the violet colour fades more rapidly. WebThe chromate and dichromate ions are fairly strong oxidizing agents. Commonly three electrons are added to a chromium atom, reducing it to oxidation state +3. In acid solution the aquated Cr 3+ ion is produced. Cr 2O2− 7 + 14 H + + 6 e − → 2 Cr 3+ + 7 H 2 O ε0 = 1.33 V In alkaline solution chromium (III) hydroxide is produced.
