WebIron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. WebPart C. The 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 ...
