You are told that a solution may contain Pb2+ and/or Sr2+.
a. How might a flame test show the presence of these ions? For each one, what
would be observed if it was present?
b. How could a precipitate test be used to determine their presence? Describe the steps that would need to be taken. Ensure you include the solutions you use for your tests.
