प्रश्न
Give one test to distinguish between the following pair of chemicals.
Sodium nitrate solution and sodium chloride solution.
उत्तर
Sodium chloride solution and sodium nitrate solution can be distinguished by using conc. Sulphuric acid to the salt solution, add freshly prepared ferrous sulphate solution and pour a few drops of conc. H2SO4 along the sides of the tube. If it's sodium nitrate solution then a brown ring would appear at the junction of the two liquid layers. But if its sodium chloride solution, it would not undergo any visible reaction.
