Document Summary
Lab 6 heavy metal precipitation: getting the lead out. The process of qualitative analysis has been used for the separation of metals from solutions by many scientists. This process separates the metals into groups based on their solubility at different solution ph"s and isolates them through selective precipitation. The precipitation can then be separated through a combination of chemical reactions and qualitative analysis to be further identified as different types of ions. The purpose of the experiment is to use of qualitative analysis as well as stoichiometry equations to allow the students to identify which three metal cations are found in a given solution. If the metals can be separated from their solutions, then type of cations remained can be identified. This will be done by using both of the processes above and they will be able to calculate the number of ions of each group of metals.
