I need to identify the cations A through G as K+, Cu2+, Ag+,Ba2+, Fe3+, Mg2+, or Pb2+
The unknown cation is Br-/OH-
From what I believed I've figured out is:
K+ = F
Cu2+ = A or E
Ag+ = B or C
Ba2+ = G
Fe3+ = A or E
Mg2+ = A or E
Pb2+ = D
I believe this may be correct but I am unable to figure outCu2+, Ag+, Fe3+, and Mg2+. I also need to make sure that they arecorrect. This lab is very confusing to me so I am trying to figureit out.

PO4 3- Insoluble Insoluble Insoluble Insoluble Insoluble Soluble Insoluble
OH- Insoluble Insoluble Insoluble Insoluble Insoluble Soluble Soluble
Unknown (Br-/OH)

I need to write a molecular, ionic, and complete ionic equationsfor each of the reaction that produced a precipitate.
