mercury (I) chromate + photos
mercury (I) chromate. It is a red powder. It doesn't dissolve in water. I made it from sodium chromate and mercury(I) nitrate dihydrate.

Nice! When I was at high school, I learned about classical qualitative inorganic analysis (and also did some lab practice). But I never worked with
Hg(I) salts and I always want to see some Hg(I) compounds. I have small amount of elementar Hg, maybe I'll try make this compound.

How stable is this? Will chromate eventually oxidize the Hg(I) to Hg(II)?

It is stable. Heat to 400 degrees Celsius as follows:
4Hg2CrO4 → 2HgCrO4 + 6HgO +O2

Holy sh*t, mercury AND chromate all in one? That's a toxicity double whammy!

Not so poisonous, because it is insoluble, the main thing is not to inhale the powder and because it is a heavy compound the powder does not stay in
the air for long.
