Greippi Posted April 24, 2010 Share Posted April 24, 2010 The most obvious solution to concentrate it that I can think of would be: Dilute the acid with a base to make some sort of nitrate salt. Then distill that with concentrated sulphuric acid. Link to comment Share on other sites More sharing options...
