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.

2. Based on Table 1, mixing the Br- solution with which of the test solutions listed below results in the formation of a precipitate having a yellow color ?

I. The Ag+ solution
II. The T1+ solution
III. The Pb2+ solution

Answer and Explanation

Your Answer is

Correct Answer is G

Explanation

According to Table 1, it can be seen that Br- and the second and third columns mix present yellow color
