This video kicked my behind.
I was getting ready to dissolve and precipitate yesterday morning to get the gold ingot on the truck to the refiner by yesterday afternoon.
But then I said to myself, "self, this would make a good teaching video".
I couldn't remember how premixed aqua regia behaved because its been so long since I used it.
During precipitation the difference is startling! The video is long, because it took so long to drop the gold from the premixed AR side of the experiment.
