It's a metal so I would say yes, therefore, it's also soluble.
PbO is amphoteric, which means that it reacts with both acids and with bases.
Magnesium oxide shows alkaline behavior.
lead oxide
There are several forms of lead oxides: Lead (II) oxide is called lead monoxide (PbO), typically used in manufacture of special glass. Lead (II-IV) oxide is called "red lead" and consists of Pb3O4 ( 2PbO-PbO2 ). Lead dioxide PbO2 is called plumbic oxide, used in dyes and in fireworks. Lead sesquioxide is Pb2O3.
Lead oxide is not a metal. Why?Lead is metal by itself, lead oxide is metal oxide, meaning it is a chemical compound that contains at least one atom of oxygen (thus oxide) and one other element (being a metal oxide, that one other element has to be metal, in this case lead).
Lead has Three type of oxides: Lead(II) Oxide = PbO (Generally referred) Lead(IV) Oxide = PbO2 Lead(II,IV) Oxide = Pb3O4
Copper oxide is unsoluble in water. A requirement for an alkali is: a soluble base. So copper oxide is a base but not an alkali.
Alkali
ITS ALKALI

Metal oxides are bases.So calcium oxide is also a base or alkali.
sodium oxide (solid) is NOT an alkali. sodium oxide forms sodium hydroxide (aqueous) is an alkali. so sodium oxide becomes an alkali only when in aqueous form and in aqueous form it is called sodium hydroxide.
Magnesium oxide shows alkaline behavior.
Acid or alkali
lead oxide
lead + oxygen = lead oxide.
Lead oxide
The positive electrode is made of lead oxide, the negative of any of the following metals: iron, lead, zinc or cadmium. The electrolyte can the hydroxides of any of the alkali metals (such as sodium). Please see the link.
