Can an acidic solution oxidize a piece of aluminum? can an acidic solution oxidize a piece of aluminum? yes no

Yes! Aluminium in acidic solution is being oxidized to its + 3 (Al³⁺) state.

Lets take example:

Make a solution of Sulfuric Acid (H₂SO₄) and add a piece of Aluminium metal in it.

2Al ₍s₎ + 3H₂SO₄ ₍aq₎ → 2Al³⁺ ₍aq₎ + 2SO4²⁻ ₍aq₎ + 3H₂ ₍g₎

In this reaction the Oxidation state of Aluminium has changed from zero to = 3, means it has lost three electrons and has got oxidized.
