Does sulfuric acid completely dissolve aluminum?

geneiusxie

Hey guys,

I was wondering if 70% sulfuric acid could completely dissolve aluminum. I know that it reacts with it, but will it form an oxide coating that prevents further reaction? Or if I tossed a brick of aluminum into a vat of 70% sulfuric acid, there won't be any solid left?

Also, what if the concentration is different, like, 30%?
Or if I used an aluminum alloy like 6061?
Thanks.
