Hay guys n girls
Somewhere on this forum I was reading a thread with pictures and information regarding AuCl It had descriptions of the content of gold roughly
as per how the colours change for example.
yellow = 0.4 - 10 grams
orange = 10-20 grams
I have searched and searched
Anybody know the thread im speaking of?
Thanks in advance.

Color is a very blunt instrument, for example a bit of palladium in solution turns the color easily towards red.
I have a vague memory of a discussion two-three years ago about the colors of different concentrations.
I didn't find it with a quick search but this is a good search to try to find it.
