I am referring to a previous answer to someone's question on "How would I set up an experiment to test for lead in candles?" Your scientist's advise was to use sodium sulfide and distilled water. Could you tell me how much of these I should use to get the right concentration for the test? Also when the solution turns turbid if lead is presence, is that because it has turned into lead sulphide? Thank you for helping me out.
