Question

Oxide has a valency of 2 then why we are writing

Lead oxide as Pbo not as Pb2o

Open in App

Solution

the lead(II) oxidation state is the more stable, and there is a strong tendency for lead(IV) compounds to react to give lead(II) compounds. And oxide oxidation state is also 2 thats why we write pbo instead of pb2O
