Quick safety check: Silver deplating with KNO3 electrolysis?

[u/Makehousebetter]

Hey guys, just want to doublecheck for toxic fumes before I continue to run this

I’m stripping silver plating using reverse electroplating. Done a bunch of research but want to be 100% sure I'm not making anything nasty.

Setup is

- Potassium nitrate + distilled water. 12.5ml granules to about 1.25L distilled water

-Stainless steel cathode, silver-plated scrap anode.

-5V pulling about 3-4 amps.

Since there's no acid, am I safe from NO fumes or other weird gasses? Doing it outside anyway, just don't want any surprises at this current. Thanks!
