hcl-cl

[arthur kierski]

i know that hcl-cl dissolves gold foils easily,and then to this liquid smb is added to precipitate the gold-----------
my question is : how does hcl-cl acts with metalics powder containing au,pd, ag and base metals?----example,hcl dissolves sn,fe ------and the liquid is trown away---- will hcl-cl be more effective or it will dissolve the pms (au,pd) together with the base metals?or the pms will remain as powders?
thanks for coments,
Arthur

Hcl/cl will behave like ar. the silver will become silver chloride. the reaction kenetics sre not as aggressive as ar but that is really contingent on particle size will the smaller pieced being more reactive.
