Chemical structure of rust
Web1 day ago · Rusting is an oxidation reaction where iron gains oxygen in the presence of water. The simplified chemical reaction is – iron + water + oxygen → hydrated iron (III) oxide (rust). 4Fe +2xH2O + 3O2 → 2Fe2O3.xH2O But why would iron react with water and air? Elements tend to have eight electrons in their outer shell for their stability. WebSep 1, 2024 · It is primarily composed of hydrated ferric oxide, so the chemical formula of rust is Fe 2 O 3 .xH 2 O .The following response can roughly characterise its formation: …
