The product form on oxidation of iron
Webb24 okt. 2024 · The oxidation of iron (II) hydroxide by the air If you add sodium hydroxide solution to a solution of an iron (II) compound you get a green precipitate of iron (II) hydroxide. This is quite quickly oxidised by oxygen in the air to an orange-brown precipitate of iron (III) hydroxide. The half-equation for the iron (II) hydroxide is straightforward. WebbThe oxidation of the iron in a ferromagnesian silicate starts with the dissolution of the iron. For olivine, the process looks like this, where olivine in the presence of carbonic acid is converted to dissolved iron, carbonate, and silicic acid: Fe2SiO4+ 4H2CO3 ↔ 2Fe2+ + 4HCO3− + H4SiO4

Webbreactant side, we add one electron to the product side. Both sides are now balanced with a +2 charge. Fe2+ → Fe3+ + e- * Note: If electrons appear on the left side of this reaction, iron is undergoing reduction and is thus an oxidizing agent. If electrons appear on the right side, iron is undergoing oxidation and must be a reducing agent.
