Question: is lead oxide a base?
Answer: Therefore, thermal decomposition of lead dioxide is a common way of producing various lead oxides. Lead dioxide is an amphoteric compound with prevalent acidic properties. It dissolves in strong bases to form the hydroxyplumbate ion, [Pb(OH)6]2−: PbO2 + 2 NaOH + 2 H2O → Na2[Pb(OH)6]
