Chemistry:Plumbite

From HandWiki

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.
