The azeotropy problem of nitric acid in water
Thread Content
Recently, I heard someone say that in nitrosulfuric acid, nitric acid and water do not form an azeotropic system (a two-component system of nitric acid and water does produce an azeotrope). I wonder if any experienced sailor out there can provide a convincing explanation.
It makes sense that nitric acid and water do not form an azeotrope in nitrosulfuric acid; the concentrated nitric acid production plants using the sulfuric acid method are based on this principle, as they take advantage of the strong water-absorbing properties of concentrated sulfuric acid to prevent the formation of an azeotrope.
