Damn it. I am out of both aqueous ammonia and nitric acid. I can make up a batch on one tonight and a batch of the other tomorrow. But it's supposed to piss rain for the next two days. I was going to do diamminedichloropalladium(II). I still might. I would just need to bubble some of the NH3 from the ammonia generator through the suspension of PdCl2. It makes a dark tan precipitate in water. Atomistry describes it as a "flesh colored precipitate". While it is indeed what anyone today would call a flesh tone I'm not sure if someone in Europe a century ago (which is when and where I think the source material comes from) would call it "flesh colored". I'm not saying it's "muh systemic racism" or anything like that. I'm just saying that people looked at things differently a century ago and I'm trying to put myself in their heads. Anyways we could go a different way with this and make up palladous sulfide PdS, filter it, dry it, and then fuse it with 12 parts KOH and 12 parts S powder to make potassium thiopalladite K2Pd3S4. I have more than enough fuel for an H2S generator. Either way I have to set up a gas generator.
