Use the following information to answer the next question. A sample solution contains two unknown ions. A student did a series of tests on the solution, in the order listed below. If a precipitate formed at any stage, the mixture was filtered and further tests were done on the filtrate. The results are as follows. First test: solution is a blue-green colour NaBr(aq) is added and a precipitate forms flame colour is violet Second test: Third test: Fourth test: Naclo,(ag) is added and no precipitate forms Two possible ions that the solution contains are O a. copper(I) and cesium O b. lead(II) and potassium O c. copper(I) and potassium O d. lead(II) and rubidium
