Thanks for pointing that out. The rout seems complex to me ???,
so I will stick with the odor then.
Concerning Mn(OH)2, in one book I found that it is brown, in
another that it is white and in the attached picture it is
yellow. What is happening here ????

These are wrong. You can see the precipitation in the video that
I posted few days back.

Thanks! Very nice video.
I hope I get a Cu2+ salt ;D.

What are the colors of aluminium and iron(III) sulfide
precipitates?

Aluminium sulfide is slightly grey in color but almost appears
colorless. I never seen Ferric sulfide though. Both are unstable
anyway.

Okay, didn't know this. What would happen if I added sodium
sulfide to a solution containing Fe3+ ions? Will anything happen
at all?

Of course, Ferric sulfide is formed. But, it slowly decomposes
into Ferrous sulfide and sulfur at room temperature.
