Lead(II) phosphate is an ionic compound with chemical formula Pb 3 (P O 4) 2. Lead(II) phosphate is a long-lived electronically neutral reagent chemical. [2] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. [3] Lead(II) phosphate appears as hexagonal, colorless crystals or ...
Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Phosphoric acid units can be bonded together in rings (cyclic structures). The simplest such compound is trimetaphosphoric acid or cyclo-triphosphoric acid having the formula H 3 P 3 O 9. Its structure is shown in the illustration. Since the ends are condensed, its formula has one less H 2 O (water) than tripolyphosphoric acid.
Lead oxides are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O). Common lead oxides include: Lead(II) oxide, PbO, litharge (red), massicot (yellow) Lead tetroxide or red lead, Pb 3 O 4, minium, which is a lead (II,IV) oxide and may be thought of as lead(II) orthoplumbate(IV) [Pb 2+] 2 [PbO 4− 4], vivid orange ...
