How do you test for presence of Barium and Iodine in aqueous solution?
To test for the presence of barium in an aqueous solution, you can add a sulfate solution, such as barium sulfate, which will form a white precipitate if barium is present. For iodine, you can add a few drops of starch solution; if iodine is present, it will produce a blue-black color due to the formation of the iodine-starch complex. Both tests should be conducted under controlled conditions to ensure accurate results.
