Question

Chemical Forensics II Group Project

Scenario: You are an engineer supervising the work on a brownfield remediation project. Just before the close of business, as you are grabbing your coat, you notice one of your coworkers left some stock solutions out on the bench. Thinking you can quickly out the awaya nd then go home,you walk over to do so, but you discover instead that the labels have not been put on the stock containers. There are labels on the counter, in glass containers, two of which contain a clear, colorless solution. The other two solutions have a dark bluish-green color.

Over to the right are a number of containers that had been used recently. These containers contain chemical compounds, in solid form, that are commonly used in your lab. They are: barium nitrate, nickel (II) chloride, potassium nitrite, iron (III) nitrate, lithium sulfate, aluminum nitrate, sodium bromide, lead (II) chloride, calcium nitrate, and mamgnesium fluroride.

Can you identify the contents of the containers and put the correct labels on the containers? Design a flowchart to show how you would test the solutions to determine what they might be. The flowchart must clearly list the chemicals needed for each test as well as show the expected test results.
