The iron is oxidized and the silver is reduced.
Ferrous iron is oxidized in the process of rust formation.
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
Iron oxide (rust) forms as the iron is oxidized.
Rust is oxidized iron.
Fe³⁺ (iron in the +3 oxidation state) is considered to be oxidized compared to its lower oxidation state, Fe²⁺ (iron in the +2 oxidation state). Oxidation refers to the loss of electrons, and when iron is oxidized from Fe²⁺ to Fe³⁺, it loses one electron. Therefore, Fe³⁺ itself is not oxidized; rather, it is the product of the oxidation of Fe²⁺.
rust
In the electroplating process, during the oxidation reaction, silver atoms are oxidized to Ag+ ions for silver plating, and iron atoms are oxidized to Fe2+ ions for iron plating. This allows the metal ions to be deposited onto the object being plated.
