You have very attractive hands.

I'll take a guess.

If there weren't so damn much of it I would say the red compound is diammonium hexachloroplatinate just like in Steve's DVD.

Sorry Steve I couldn't resist :wink: :lol:

Very impressive Lou. What's it weigh?

 

[Noxx]

Same guess than qst42know.

I think it's a beer......

Answers from left to right:

125g or so of 99,999 AgNO3
500g of potassium dichromate (if it were ammonium hexachloroplatiante, it would be canary yellow)



Thanks for the comment about my hands. You know, before I was a chemist, I was a hand model for chemical gloves (Not really)


And Randy, I have better lab hygiene than that! I could sure use a cold one after some of these days I've had lately, but not in the lab.

I need to watch that DVD several more times.

On the Pt DVD the Platinum ammonium chloride that I precipitated was a red orange color. The platinum was from a dental crown. A second refining would have likely produced a more yellow colored powder as seen in the youtube video slide show I posted. In this video the platinum salt was very nearly canary yellow.

The color will range from canary yellow through orange to a deep maroon. Do not be surprised if the shade is different every time; it depends upon the temperature at which it forms, the impurities present, and other factors as well.

If Rhodium is present it can even have a tint of green.
