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 w filtered and further tests were done on the filtrate. The results are as follows. First test: solution is a pink colour NaIO3(aq) added and no precipitate forms Second test: Third test: flame colour is red Fourth test: NazCO3(aq) is added and no precipitate forms Two possible ions that the solution contains are a. lithium and cobalt(II) O b. strontium and cobalt(II) Oc. lithium and manganese(II) O d. strontium and manganese(II)
