Plumbite
From Infogalactic: the planetary knowledge core
In chemistry, plumbite is the PbO2 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:[1]
- PbO + OH−
→ HPbO−
2
Lead(II) hydroxide also dissolves in excess alkali to form the Pb(OH)4−
6 anion:[2]
- Pb(OH)
2 + 4 OH−
→ Pb(OH)4−
6
The plumbite ion is a weak reducing agent. When it functions as one, it is oxidized to the plumbate ion.
