Exclange Ica 3. A student is given an unknown to identify. The unknown is colorless, odorless, and neutral. It produces no precipitates when reacted with any of the three halides, Cl-, Br, and I. It produces a yellow precipitate when added to sodium chromate. Which of the following could it be? Write its exchange reaction with sodium chromate. HCI NaOH NH,OH BaCl, K,CrO, AgNO, NISO, 4. A second student in the lab is given the same list of possibilities as the student in question 3 above. This unknown, while also colorless, odorless and neutral, gave a brownish precipitate when mixed with NaOH, and a white precipitate when added to BaCl,. Reactions with the other halides gave yellow precipitates. What unknown do they have? Write the equation for the exchange reaction with the unknown and NAOH. Also, write the balanced reaction between the unknown and BaCl,.
