Comment on Can acidic and carbonated drinks corrode aluminium bottles?

This is completely false. The lining is so the metal can’t be broken down by whatever is in it. Without it contaminants can leach into the product, or even dissolve the can.

Leave water in those non coated metal containers long enough and it’ll leach from the metal.

in some cosmic sense yeah there will be equilibrium after some time but most of the time it’s just called “corrosion”

  I believe the distinction is necessary, corrosion would be the entire bottle “dissolving” which wouldn’t happen with water. With leaching only a few elements would transfer.

    What? Corrosion is the surface oxidizing, not the entire thing dissolving.

    When the surface oxides, that layer get removed, than the surface oxides, that layer disappears. Repeat ad-nauseam until it’s completely gone.
    
    Dissolving is oversimplifying, but eventually the entire thing will disappear with corrosion.
