Hi, I have a queastion :
I have some silver palladium alloy contacts from relay(a lot from a USSR phone central) this from photo,
I dissolve this in nitric and drop the silver with HCl and after I add some urea and ammonium chloride to check platinum if is present (negative) I check the solution with sncl and the colour is turn in brown black(this mean possitve for palladium) and I try to bubble some chlorine gas in solution to drop palladium and is not happen nothing (I DONT CONCENTRATE THE SOLUTION AND I DISOLVE THE CONTACTS WITH THAT BASE METAL FROM PHOTO WICH I BELIEVE IS NOT COPPER and I try to drop with alluminium and form a dark grey slug)
Trying to drop palladium with chlorine if the solution contain base metals is a problem?
What to make to get the palladium out from solution (I don't have access to DMG and sodium chlorate and formic acid , I have only 12.5%ammonia)?
Dropping with alluminium from that solution and after boil the slug in in hcl and dissolve back in small amount of nitric and try again to bubble chlorine(after denox) will work to get red brick palladium salt ?
