Fill out the chart please.
Now let us work on the left-hand branch of the flow chart containing the supernatant with the remaining four catto Cr. zn.NP, Mg(note, the presence of Nat should have already been flame tested, its presence here will not interfere with subsequent tests on the remaining ions.) We should keep in mind that our unknown could contain any number of these ions and thus we will need a procedure (flow chart) that can help us separate...
