Respuesta :
Aluminum can be oxidized by [tex]Li^{+}[/tex] and [tex]Ca^{2+}[/tex]
What is oxidizing?
Some of the metal corrodes (or oxidizes) and forms the corresponding metal oxide on the surface as a result of a chemical reaction between the metal surface and the oxygen in the air. The corrosion products that occur in some metals, like steel, are highly apparent and loose.
According to reactivity series (The array of metals in the descending order of their reactivities is referred to as the metals' reactivity series. It is sometimes referred to as the metals in the activity series.)
Lithium and calcium ions are more reactive than aluminum ion and they are less electronegative.
Since silver and tin are more electronegative than aluminum so, they cannot oxidize aluminum.
∴ [tex]Li^{+}[/tex] and [tex]Ca^{+2}[/tex] ions can oxidize aluminum.
