QUESTION 7 The following solution was analyzed according to the scheme used in this experiment. Identify the anion present based on the following observations: Silver Nitrate Test: Off-white precipitate formed, which dissolved in dilute HNO3. Barium Chloride Test: White precipitate formed which dissolved in dilute HCl. Chlorine Test: After treatment with chlorine water, the mineral oil layer was colorless. Cl- Br- I- SO42- CO32-

Writing Balanced Molecular, Ionic, And Net Ionic Equations Write Balanced Net-Ionic Equations for the following Reactions in Aqueous Solution: 1. Copper metal (Cu(s)) is immersed in an aqueous solution of silver nitrate (AgNO3). The solution turns light blue and a silver coating appears on the copper. 2. Dilute solutions of antimony(III) chloride and sodium sulfide are mixed to give a precipitate. 3. Dilute solutions of silver nitrate and potassium iodide are combined and give a yellow precipitate. 4. Dilute solutions...
