  2. Isotopes of lead - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_lead

    Lead (82 Pb) has four observationally stable isotopes: 204 Pb, 206 Pb, 207 Pb, 208 Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide.The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series ...

  3. Lead - Wikipedia

    en.wikipedia.org/wiki/Lead

    Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when ...

    Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 2− 4 to a solution containing 0.1 M of Pb 2+. The pH of the solution is 4.5, as above that, Pb 2+ concentration can never reach 0.1 M due to the formation of Pb(OH) 2. Observe that Pb 2+ solubility drops 10,000 fold as SO 2− 4 reaches 0.1 M.

    Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow Pb 12 O 19 , monoclinic, dark-brown or black crystals The so-called black lead oxide , which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries .

    en.wikipedia.org/wiki/White_lead

    White lead is the basic lead carbonate 2PbCO 3 ·Pb(OH) 2. [1] It is a complex salt , containing both carbonate and hydroxide ions. White lead occurs naturally as a mineral, in which context it is known as hydrocerussite , [ 1 ] a hydrate of cerussite . [ 2 ]

  8. Lead(II) acetate - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_acetate

    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 + H 2 O. Lead(II) acetate can also be made via a single displacement reaction between copper ...
