Gold seems like an interesting element to get in solution and observe, but I lack aqua regia to dissolve it in, and I refuse using sodium cyanide. Does anyone know some alternate ways to dissolve gold?
Okay, I have one idea but I need to know if it's right. If I put some small flakes of gold I have (panned some), in a small vial, and added Hydrochloric acid and commercal hydrogen peroxide, and it would produce small bubbles of Chlorine that would form on the gold. The amount of Chlorine being produced shouldn't be very dangerous with literally a fifth of a small vial of this solution. Gold, like most metals, would react directly with a halogen, right. And this reaction would yield Auric Chloride.
Another idea, similar to the above, I would place some gold in a Tincture of Iodine solution. Iodine isn't as reactive, but it's a halogen.
