Stupid silver Stupid me

[No-luck]

Hello everyone been on this forum on and off for a few years give or take a few years. First time posting .So I dissolved some 925 in 67% NO3 worked like a charm dark blue solution crystal clear. Proceeded to precipitate silver chloride with HCL 32% no white at ALL. I’m assuming either nitric was spent or not enough HCL…. What now? Now my solution is a deep emerald green. Just perfectly perfect.

Not sure what's up with your Hydrochloric, but you can try a saturated salt solution (table salt is fine).

Welcome to us.
Are you sure it is HCl?
Dissolved Silver will grab any Chloride and crash out as Silver Chloride. Quite immideately.
As Eaglekeeper says, plain table salt will do well.

Assuming your acid is Hydrochloric Acid if it was Silver you would definitely see the white Silver Chloride. So how do you know the metal was Silver? The solution turning green may be telling us something. Palladium would dissolve completely as well. Can you test a few drops with Dimethylglyoxime?

Behaves like German silver (not sterling silver), green...copper, blue...nickel. No white precipitate...no silver. Sure you have sterling silver?

I think the thing in question is definitely the alloy dissolved. I suggested Palladium because it will behave that way in nitric and it will also plant seeds of optimism for someone with no luck!
