Can we boil concentrated or diluted nitric acid in aluminum pot when we try to make copper parting?
Glassware beakers some times when boiling metallic shots with nitric get break, because of shots slime at the bottom of the beaker some times make an isolation layer so solution not reach to the glass bottom surface.
I read that nitric acid when touch aluminum it makes Al2O3 layer at the surface, but if that is true, we can also add sulphuric acid to aluminum pot after Al2O3 formed on the surface because of nitric, isn't it?
