Cu is being reduced and Zn is being oxidized, hence
Zn + CuSO4 --> ZnSO4 + Cu
Zn is being iodized and Cu is being reduced
Fe3+
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
The element that is oxidized in the reaction 4Al + 3O2 → 2Al2O3 is aluminum (Al). In this reaction, aluminum loses electrons and undergoes oxidation to form aluminum oxide (Al2O3).
Which element will be oxidized and which will be reduced
Oxidation involve loss of electrons and reduction involve gain of electrons.
