Unformatted text preview: 2 Identity Ki Double unknown number 4 Identity NaCl+ KBr Discussion: This lab was very simple. My partner and I got through it very quickly. There weren’t many sources of error, however, 1) Out of carelessness, we stirred 2 different ions with the same toothpick. 2) It could have already had contamination from the previous period. 3) We put more than 5 drops by squeezing the dropper too hard. Conclusion: I learned that halide ions react differently with different reagents. My hypothesis was correct. Questions: 1. Which procedure confirms the presence of (a) Cl- ions, (b) Br- ions, and (c) I-ions. a) When you add AgNo3 and NH3 into the NaCl. b) All the halide ions being added to KBr. c) All the halide ions being added to Ki....
