Nitrate test using acid. Nitrogen dioxide fumes (orange) are produced when concentrated sulphuric acid is added to moistened copper turnings (green) and nitrate-containing chemicals,which are then heated. This is a test for the presence of the nitrate group in a chemical. The acid is extremely corrosive and nitrogen dioxide is toxic,so safety precautions are needed when carrying out this test | |
