interested to find out whether a silver wire is pure silver or contains other metals like iron/copper
cuz apparently the wire is attracted to magnets
so.. can anyone devise a simple chemical test to show this?
i've access to various reagents, acids etc.
will 10M HCL be a good option? considering if silver is non soluble in 10m HCL whilst other metals would probably react
what should i use to precipitate the other ions? iron? copper?
