Solution
Sodium chloride solution and sodium nitrate solution:
Add freshIy prepared ferrous suIphate solution to the two solutions. Then by the side of the test tube, pour concentrated sulphuric acid to each slowly. The one in
which brown ring appears is sodium nitrate solution while the other is sodium chIoride solution.
