The pink precipitate Of Mn(OH)2 gets oxidized when exposed to air then it turns dark brown, and has become
MnO(OH), which is manganese III oxyhydroxide. Thats a mouthful!

I answered that question earlier this evening, although for someone who asked later. Why should two people be asking this unusual question? I'd really like to know.
