Potassium Ferricyanide (used to test FO) is
K3Fe(CN)6
This works well for testing the FO as outlined in my guide (available at
link below).

Potassium Ferrocyanide is
K4Fe(CN)6
I do not know what this will do as I have not used it.  I suspect that
it's valence may not be appropriate for the testing.
Perhaps a chemist on the list will respond.

A letter or a number may make a world of difference.
