Sandy, I believe that you will find that there are many formulas that
various people use for their palladium solution. It is quite soluble
and can be mixed at a variety of dilutions. I believe that everyone has
their own reasons for doing so. I mix mine with a bit more gusto than
Carl. 5g makes 40mls for me.

Sandy,
The platinum solution is nominally 20%, but the palladium solution is
less
than 10% palladium chloride. I think if you mix it from
palladium-sodium-chloride, which is more expensive than palladium
chloride
plus sodium chloride, that is something like a 17% solution.---Carl
