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 ...

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.
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.
Lead(II) oxide gives a mixed oxide on further oxidation, Pb 3 O 4. It is described as lead(II,IV) oxide, or structurally 2PbO·PbO 2, and is the best-known mixed valence lead compound. Lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas. [77]
Lead(II) acetate can be made by boiling elemental lead in acetic acid and hydrogen peroxide. This method will also work with lead(II) carbonate or lead(II) oxide. Pb + H 2 O 2 + 2 H + → Pb 2+ + 2 H 2 O Pb 2+ + 2 AcO − → Pb(OAc) 2. Lead(II) acetate can also be made by dissolving lead(II) oxide in acetic acid: [7] PbO + 2 AcOH → Pb(OAc) 2 ...
