There are other colors than that.

Not that we are interested in.

Three test tubes on 3 different occasions is not a false positive.

It is usually cased by SO₂ or Copper

Gold and silver

There will be no Silver if you used AR as Silver will form AgCl which is not soluble.
Anyway since you have not said at which pH you stopped the addition of NaOH we have no idea which hydroxides you have dropped

He means brown is a reaction of copper chloride to stannous chloride. Called a false positive. To see if there is any purple(gold), dilute the test drop.

None of that was present

I didn't ask for the identification of my hydroxides. I asked for people to see if they recognize the pgm from my pictures. I am not a newbie and don't need help with my process. I'm just trying to see what pgm I have. That's all. Please see the pictures

No copper was present. I tested 3 different times on different occasions and got the same color. Then I dropped the gray powder in the picture

But everyone is missing my actual question.

The pictures are useless.
Get your stuff tested with a XRF or an ICP or other spectral instrument.

We can not help more, since you are not willing to help us help you.

 

[MindyBeatty]

Lol. Thanks anyways.

No we are not missing your question, but we have not enough information to help you.
Anyway blurry images are useless in this kind of scenarios.

Maybe you need glasses then

I have not said anything regarding Urea, even though we prefer Sulfamic acid.
And we do not call that neutralizing because that is to bring the solution to 7 which is neutral.
We call it deNOxing since we decompose the NOx to avoid re dissolution.

Red is probably colloidal Gold.
Add a splash of Peroxide into your HCl and it will dissolve.
Just that you will never see it since it is so small amounts.

Gold is not metallic silver color

So this forum is only about what you are interested in?

You can start with finding the SG and such mechanical properties.
At least it is one end to start in.
There have to be some kind of pawn shop, we buy Gold shop or similar you can take it to and get it shot with a XRF

There is nothing in my area

Colloidal Gold has many colors and I was referring to your red solution.
Metallic Gold is not Silver in color, we know that.

You will have to try and get the SG then.

My solution isn't red as I've already dropped the gray powder and now this black with a reddish undertone. All I have now is solids.

Which is?
