Passage I
The 4 common halide ions are fluoride (F-), chloride (C1-), bromide (Br-), and iodide (I-). A halide in solution can be identified by mixing the solution with various test solutions and observing the precipitates (solids), if any, that form.
Table 1 shows the results of mixing each of 4 colorless aqueous halide solutions with a colorless aqueous test solution containing calcium (Ca2+), silver (Ag+), thallium (T1+), or lead (Pb2+).
Table 2 shows the results of mixing each of 2 colorless aqueous solutions (A and B) with each test solution. Each of Solutions A and B is a combination of 2 of the halide solutions.
3. When sodium iodide (Nal) is dissolved in water, Na+ and I- ions are produced. Based on Table 1, mixing a colorless aqueous solution of Nal with the Ag+ test solution would most likely result in the formation of:
Your Answer is
Correct Answer is B
Explanation
According to Table 1 I- and Ag+ mix will have cloudy yellow precipitate
