Procedure : Refer to pages 32-34 of General Chemistry Laboratory Experiments, Volume 1 by Robert Tatz and Judith Casey, Hayden-McNeil Publishing 2012. Report Sheet : See attached report sheet. Report Questions : 1. The charge on the iodide ion is 1-. The charge on the lead ion is going to be 2+. The formula for lead sulfide PbS. 2. The charge of the chromium ion is 3+. The charge of the second chromium ion is 2+. The first compounds name is chromium (III) phosphate, and the name of the second compound is chromium (II) phosphate. 4. No, there would be excess ions in all of the test tubes. You would have to add 18 drops of sodium phosphate to the 12 drops of tin chloride to get the proper ratio of 3:2. The equation is: 7. Yes, the tube that would have no ions in excess when potassium iodide was
