Problem of the week - 29/04/2013

Borek:
1.000 g of a roasted salt decomposes producing three oxides - 0.878 g of a solid one, 0.0354 g of a liquid one and 0.0866 g of a gaseous one (at STP).

Determine the salt identity.

Rutherford:
I got Pb(OH)2·PbCO3 or (PbOH)2CO3, not quite sure  :-\.

Big-Daddy:

Surely this can't exist ... That would mean the (PbOH)+ ion exists which I doubt.

Rutherford:
Okay, then maybe the first one.

Big-Daddy:
Borek when you say oxides do you just mean the salt contains oxygen in some form, or specifically the O2- ion? (Or can you not tell us?)
