Molar magnetic susceptibility ... is a chemical element; it has symbol Pb (from Latin ... Natural lead consists of four stable isotopes with mass numbers of 204, 206 ...
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 ...
Pb(C 2 H 3 O 2) 2 : Molar mass: 325.29 g/mol (anhydrous) 379.33g/mol (trihydrate) Appearance White powder or colourless, efflorescent crystals Odor: Slightly acetic
Pb is used in HCl service even though the PbCl 2 formed is slightly soluble in HCl. Addition of 6–25% of antimony (Sb) increases corrosion resistance. [16] A basic chloride of lead, PbCl 2 ·Pb(OH) 2, is known as Pattinson's white lead and is used as pigment in white paint. [17]
Molar mass: 223.20 g/mol Appearance red or yellow powder Density: 9.53 g/cm 3: ... also called lead monoxide, is the inorganic compound with the molecular formula Pb O.
PbO + 2 HNO 3 (concentrated) → Pb(NO 3) 2 ↓ + H 2 O. It may also be obtained evaporation of the solution obtained by reacting metallic lead with dilute nitric acid. [11] Pb + 4 HNO 3 → Pb(NO 3) 2 + 2 NO 2 + 2 H 2 O. Solutions and crystals of lead(II) nitrate are formed in the processing of lead–bismuth wastes from lead refineries. [12]
In aqueous solution, lead(II) hydroxide is a somewhat weak base, forming lead(II) ion, Pb 2+, under weakly acidic conditions. This cation hydrolyzes and, under progressively increasing alkaline conditions, it becomes somewhat weak acid, and it forms Pb(OH) +, Pb(OH) 2 (aqueous), Pb(OH) − 3, and other species, including several polynuclear species, e.g., Pb 4 (OH) 4+ 4, Pb 3 (OH) 2+ 4, Pb 6 O ...
2 is commonly synthesized via a precipitation reaction between potassium iodide KI and lead(II) nitrate Pb (NO 3) 2 in water solution: Pb(NO 3) 2 + 2 KI → PbI 2 + 2 KNO 3. While the potassium nitrate KNO 3 is soluble, the lead iodide PbI 2 is nearly insoluble at room temperature, and thus precipitates out. [17]
