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.
| A | B | C | D | E | F | G |
Br- | Soluble | Insoluble | Insoluble | Soluble | Soluble | Soluble | Soluble |
SO4 2 - | Soluble | Soluble | Soluble | Insoluble | Soluble | Soluble | Insoluble |
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.
Reaction 1 - 13
For example,
