Slowly evaporate the acid mix, under a vacuum exhaust with all protections. Do not go to dryness. Stop a bit before. Redissolve in pure water and re-evaporate. Repeat the last step if the solution is still too acidic.
That's what I remember without checking my notebooks.

|Hi,
|
|
|Does anyone of you know a procedure to make gold
|(III)-chloride from pure
|gold? I know, that gold has to be dissolved in aqua regia. But
|how should I
|get solid gold chloride out of the aqua regia? Any ideas are welcome.
|
|Thanks
