Plumbite
In chemistry, plumbite is the PbO2−2 oxyanion or hydrated forms, or any salt containing this anion. In these salts, lead is in the oxidation state +2. It is the traditional term for the IUPAC name plumbate(II).
For example, lead(II) oxide (PbO) dissolves in alkali to form salts containing the HPbO−2 anion (hydrogen plumbite):[1]
- PbO + OH− → HPbO−2
Lead(II) hydroxide also dissolves in excess alkali to form the [Pb(OH)6]4− anion (hexahydroxyplumbate(II)):[2]
- Pb(OH)2 + 4 OH− → [Pb(OH)6]4−
The plumbite ion is a weak reducing agent. When it functions as one, it is oxidized to the plumbate ion.
