Lead(II) sulfate (PbSO 4) is a white solid, which appears white in microcrystalline form.It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.. It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the ...
Lead(II) thiocyanate – Pb(CNS) 2; Lead(II,IV) oxide – Pb 3 O 4; Lead(IV) oxide – PbO 2; Lead(IV) sulfide – PbS 2; Lead hydrogen arsenate – PbHAsO 4; Lead styphnate – C 6 HN 3 O 8 Pb; Lead tetrachloride – PbCl 4; Lead tetrafluoride – PbF 4; Lead tetroxide – Pb 3 O 4 [205] Lead titanate – PbTiO 3; Lead zirconate titanate ...

Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide.
It dissolves in nitric acid with the evolution of nitric oxide gas to form dissolved Pb(NO 3) 2. 3 Pb + 8 H + + 8 NO − 3 → 3 Pb 2+ + 6 NO − 3 + 2 NO + 4 H 2 O. When heated with nitrates of alkali metals, metallic lead oxidizes to form PbO (also known as litharge), leaving the corresponding alkali nitrite. PbO is representative of lead's ...
[2] Lead arsenate was the most extensively used arsenical insecticide. [3] Two principal formulations of lead arsenate were marketed: basic lead arsenate (Pb 5 OH(AsO 4) 3, CASN: 1327-31-7) and acid lead arsenate (PbHAsO 4). [3] It is now banned for use as a pesticide in countries such as the US and UK as it is considered too toxic and persistent.
Addition of hydrogen sulfide or sulfide salts to a solution containing a lead salt, such as PbCl 2, gives a black precipitate of lead sulfide. Pb 2+ + H 2 S → PbS↓ + 2 H + This reaction is used in qualitative inorganic analysis. The presence of hydrogen sulfide or sulfide ions may be tested using "lead acetate paper."
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.
