Vuaquelin’s salt

[Inter Refiner]

Hello,
Every time when I dissolve pd salt in ammonia ,after precipitating it by chlorine gas, vuaquelin’s pink to muove (purple) salt is formed,

How can I avoid forming this salt and dissolve all pd into ammonia, I tried to use more ammonia and I tried heating it but nothing kept that pink stubborn salt from forming.

The chlorine oxidizes Pd++ to Pd++++. There's no way to avoid...

Boil the ammonium chloropalladate to decompose it from (IV) to (II) [PdCl6]2- --> [PdCl4]2- + Cl2.


FYI, the pinkpurple will eventually dissolve.
