1. A student was performing the test for chloride in his unknown. When he added the five drops of HNO3, he observed bubbles forming (effervescence) in his unknown. Was chloride present in his unknown? How do you know? A student added barium chloride to her unknown and immediately witnessed the formation of a precipitate. She concluded that this white precipitate indicated the presence of chloride ion in her unknown. Is she correct? How do you know? A student has two unlabeled bottles of solution. One contains PO,3 and the other SO,²'. How can this student identify which is which?
