Question:
My mom has a serving plate that is silver plated. For my science project I would like to remove the silver. how do I do that?



Replies:
You better be sure your mom is OK with losing a silver plated serving dish, because I am assuming from your question that you want to permanently remove the silver, not just polish it.

You will not recover a lot of silver because the amount plated is usually very small. Some attention has to be paid to what is the base metal being plated because any of the de-silvering methods may also dissolve the base metal. Finally, from the recipes below you see that the de-silvering process makes use of some pretty nasty acids -- nitric and/or sulfuric. You will need help from your science teacher in order to obtain those reagents and to handle them safely.

Evan,

That is a tall order for home chemistry. I think you would be safer and have better results if you had your science teacher let you do this work at school.
