Plumbite
In chemistry, a plumbite is a salt having one of several lead-containing oxyanions in which lead is in the oxidation state +2. The term plumbite may also refer to the oxyanion itself. 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.
