plumbate

In chemistry, a plumbate is a salt having one of the several lead-containing oxoanions.

When it functions as one, it is oxidized to the plumbate ion.

All plumbate(IV) salts are very strong oxidising agents.

Under law's marshall and warschouw did I thole till lead's plumbate, ping on pang, reliefed me.

According to surface ceramic vestiges (Plumbate), the last occupation would be linked to the maximum Toltec expansion.

Iron and steel can also be primed with these materials for interior work, but for exterior work calcium plumbate primer is best.

It dissolves in strong bases to form the hydroxy plumbate ion, Pb(OH):

Some hydrated plumbate(IV) salts decompose upon dehydration.

In strongly alkaline solutions soluble plumbate ions are formed, including [Pb(OH)].

The lead-based pigments (lead tetroxide/calcium plumbate, or "red lead") were widely used as an anti-corrosive primer coating over exterior steelwork.

Calcium plumbate primer can also be used on galvanised iron, but zinc chromate or zinc phosphate is used on aluminium alloys.

Other amphoteric metals are zinc and lead which dissolve in concentrated sodium hydroxide solutions to give sodium zincate and sodium plumbate respectively.

Exhibits in the museum from this era include plumbate pottery which has orange and grey tones and depicted lives of animals and supernatural entities of their surfaces.

Long range contacts are indicated by the appearance of ceramics from eastern Mesoamerica, grey-green plumbate from southern Guatemala and polychrome ceramics from Costa Rica.

Fragments of an Early Postclassic plumbate ware vessel were recovered scattered around three sides of the temple that were probably the remains of a relic from within the temple itself.

Traits associated with this horizon are: The Mixteca-Puebla style of iconography, Tohil plumbate ceramic ware and Silho or X-Fine Orange Ware ceramics.

In solution, lead(II,IV) oxide can be prepared e.g. by reaction of potassium plumbate with lead acetate, yielding yellow insoluble lead(II,IV) oxide monohydrate, PbO HO, which can be turned into the anhydrous form by gentle heating:
