Sodium orthoargentite. Green compound
It's very strange to me that sodium orthoargentite has a light green color. It is very easy to make.
Ag2O + 3Na2O = 2Na3AgO2
Unfortunately, I do not have time to do it. Also i do not have sodium oxide and I will have to get it from sodium azide.
I think it is worth. Even because of the color. It is a rare compound. The reaction is carried out in a vacuum.

Sometimes these orthosalts have quite different colours than their meta analogues. Look at perrhenates: metaperhenates ReO4- are colourless,
orthoperrhenates (ReO5)3- are yellow if I remember it right.

you are right. Yellow is even more understandable when we talk about rhenium. But the green color from such metals?

Why not? Silver is also transition metal.

Yes I know, but I think green is unusual.

Because it's a d10 system, and is expected to be colourless in the absence of charge-transfer bands (which you normally only get with higher oxidation
states or easily reduced ions).
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Sorry, I didn't realized that.
