Chrome Plating
« on: April 11, 2013, 12:26:35 AM »
Chrome plating is very common. A variety of commonly handled items are chrome plated for instance scissors. If scissors are handled, used to cut food items etc... Doesn't the hexavalent chromium  used in plating pose a toxic risk?

There is no hexavalent chromium in the final product.

Yes, it can be dangerous to those involved in production, if they fail to follow safety procedures.

Ok. What does the hexavalent chromium become? Trivalent chromium is also used in plating, what does that become in the final product?

Inert, metallic chromium.

You are again looking for non existing toxicity using non existing chemistry, it is a waste of time.

The product gets covered by a thin layer of chromium atoms. It is a metal. Once exposed to air, the chromium forms a thin layer of oxide that protects the chromium under it from oxidizing further. The layer is very thin and not visible to the eye.
