Multiple questions about the drop.
1) I did two today using SMB. The first...big chunks of gold. The second...slow, fine gold.
2) What are the situations that produce big chunks vs the fine stuff that takes forever to settle?
3) Also...is dropping with SO2 really as simple as just putting a hose in the beaker and letting it bubble? Does it work on excess nitric as well?
4) This is so much fun I'm thinking about building an SO2 generator. Is anyone using one? Is it really necessary to bubble the SO2 through concentrated H2SO4...I mean, it's being bubbled in to an aqueous solution.
5) Finally, does my copperas look right? It wouldn't go in to solution with water, so I added sulfuric acid to it and heated it. It did this really cool boiling thing where the whitish layer would boil underneath the sulfuric acid...then when cooled it did this. The whitish layer SEEMS to be solvent in the water/sulfuric above...if you break in to it and start stirring. (picture is on cell phone, so I have to post this, then post picture)
Both beakers are essentially the same, just two batches.
