Question

What is the valency for plumbite?

Answer 1

Explanation:

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:[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.

Answer 2

Answer:

the valency of plumbite (na2pbo2) is +3
