Gold can be made to tone in both alkaline and acidic solutions. Platinum
tends to be way too active in alkaline solution, palladium even more so --
therefore, they are generally used in acidic baths. When using gold
followed by platinum, I have had better results with alkaline (borax) gold
toners. FWIW, even in acidic solutions I have had problems with palladium
depositing a dichroic fog of colloidal palladium indiscriminately on the
print (and often, the tray).

Here are a few links (some of these may word-wrap and need reconstruction):
