3 molar Nitric Acid?

What's your thoughts? Can that clean a penny or WHAT

Or what! It will give you a lot of copper nitrate and not much penny.

 

well the old ones anyway. Wonder if that stuff can be used to crack open a slab..

 

"That stuff" is nitric, I assume. Just an educated guess (barely educated), those slabs are polycarbonate. If that is correct,you won't find chemically to affect it

 

Might try mixing it with glycerin. Maybe a new method to cleaning coins.

plus a pinch of sulfer and phosphorous

 

Yeah, try carrying those on an airline.

They are the key ingredient to toothpaste

 

can one clean their coins with toothpaste?

 

What kind of toothpaste do you use ??? Kitchen Matches Flavored Crest?

Jim

 

I don't know. Baking Soda, Sodium Laural Sulfate, SPAN-60, Mint Flavering, Sulfur, Phosporus and for that extra burst of energy in your smile and polishing action, 3 molar Nitric Acid.

Ahhhhhhhhhh, nitric acid and copper.
A fun combo.
I remember in college chemistry class one of the guys dropping a cent (no clad cents at that time) in concentrated nitric acid.
Very interesting browish gas released.
He had it cleaned up by the time the instructor got there.

 

Use it for awhile and you have two molar, awhile longer one molar. Then no more molar and we start working on bicuspid nitric acid.

 

Thah Dump...

 

I remember dissolving pennies in chemistry with the 18 molar nitric the teacher had "locked" away in the lab room.

 

and for good reason

 

Very interesting poisonous gas released ! Nitric Oxide.

 

I hope everyone that posted here knows that Homeland Security has now tapped your phones and has a surveillance truck parked down the street from your house. :whistle:

About a dozen wrong things were said.

Actually, that very poisonous brown gas is not nitric oxide (nitrogen monoxide), it is nitrogen dioxide. Nitric oxide is produced in dilute nitric acid, along with copper nitrate and water, turning the solution blue.

The CENT, however should be left with some kind of copper oxide layer if dipped "properly", if there is such a way with nitric acid. I would assume if not rinsed immediately, that you would end up with either a clay red or black layer. If this could be avoided, there should be a good protective layer that should stop any corrosion, verdigris, or PCV damage that may have been on the cent.

As far as cleaning is concerned, I would guess it would depend completely on what exactly you are trying to clean off and the reaction those substances would have with the acid. You could very well end up with an explosion if you have large enough traces of certain other substances.
