Probably not of much interest to anyone who doesn't need to remove oxides from copper or silver, but perhaps useful for those who do.

Few days ago I had one of those cups for water on my kitchen table where I used it for some quenching and I drank from it on accident twice in a row, it didn't even look like the cup I use for water

I left my gold plated brass jump rings in sodium Bisulfate pickle which ratio was 1/8 cup of pickle to 1 cup of water and the jump rings came out black still. Can anyone tell me why this happened I have spent all day sanding the jump rings with 600 grit sand paper and than using the pro polish pad I'm halfway done I got two jump rings completely clean and the chain is halfway done

since phosphoric is a prime component in coca cola, I'd add it to the test as it usually has carbonic acid too, I think.

Great video! Is sodium bisulfate the same thing as baking soda?
@esalenchik6 жыл бұрын
Aubrey Mascali Baking soda is sodium bicarbonate, so it’s a different thing. I believe sodium bisulphate is available from swimming pool supply stores.

Nice comparison ! , Can we use muriatic acid as pickling solution ?
@MatBrown5 ай бұрын
Yup. Any acid will work. I did have some HCl around but didn't include it in the test because it was in some weird gel form for applying to tiles..

@@MatBrownActually, as you said, if you paid attention in Chemistry class you would know the Salt breaks down into Na and Cl, which then accepts a H molecule from the Acetic acid (vinegar) and becomes Hydrochloric Acid ... which is why it works so good!

what concentration was your phosphoric acid before you diluted it?

81%. Pretty strong.

The ph down is that from an aquatic shop for fish? Great video thanks
@MatBrown3 жыл бұрын
I think the pH down I'm using here is from a hydroponics suppliers. To the best of my knowledge there are two things commonly sold as pH Down - sodium bisulfate and phosphoric acid. I know that pH Down for swimming pools is sodium bisulfate, and the pH Down for hydroponics is phosphoric acid. Your aquatics shop should be able to tell you what they stock.

I wonder if coca-cola would have worked?

Almost certainly. It's very acidic, but it's also quite sticky.

Not that I'm aware of. Although I use it in a cheap ultrasonic cleaner which has a lid, so I probably wouldn't notice if it did.

Nitric acid for copper.
@bruceakers70035 жыл бұрын
too strong & more dangerous, will start etching; nitric & sulfuric acids mixed = dutch mordant for etching steel in my past experiences.

Nitric acid and copper would create a volatile reaction i believe. I used to mix copper with 32% hydrochloric acid to create nitric acid
