In chemistry, iron (II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro- is often used to specify such compounds, as in ferrous chloride for iron (II) chloride (FeCl2). The adjective ferric is used instead for iron (III) salts, containing the cation Fe 3+.
Hemoglobin, the protein responsible for carrying oxygen, contains iron in its ferric state. The iron in ferric ions binds to oxygen molecules, allowing for efficient oxygen delivery to tissues throughout the body. Ferrous ions, on the other hand, are involved in various enzymatic reactions.
Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') 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, forming much of Earth's outer and inner core.
30 cze 2023 · The overall equation for the reaction is: S2O2−8 + 2I− → 2SO2−4 +I2 (2) (2) S 2 O 8 2 − + 2 I − → 2 S O 4 2 − + I 2. For the sake of argument, we'll take the catalyst to be iron (II) ions. The reaction happens in two stages. S2O2−8 + 2Fe2+ → 2SO2−4 + 2Fe3+ (3) (3) S 2 O 8 2 − + 2 F e 2 + → 2 S O 4 2 − + 2 F e 3 +.
