Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S. Galena is the principal ore and the most important compound of lead . It is a semiconducting material with niche uses.
Lead sulfide refers to two compounds containing lead and sulfur: Lead(II) sulfide , PbS, containing lead in the +2 oxidation state, naturally occurring as the mineral galena Lead(IV) sulfide , PbS 2 , containing lead in the +4 oxidation state
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5] Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.
2) salts of lead. The sulfide can also be precipitated from acetate solutions. These salts are all poorly soluble in water. Among the halides, the iodide is less soluble than the bromide, which, in turn, is less soluble than the chloride. [3] Lead(II) oxide is also soluble in alkali hydroxide solutions to form the corresponding plumbite salt. [2]
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) hydroxide – Pb(OH) 2; Lead(II) iodide – PbI 2; Lead(II) nitrate – Pb(NO 3) 2; Lead(II) oxide – PbO; Lead(II) phosphate – Pb 3 (PO 4) 2; Lead(II) sulfate – Pb(SO 4) Lead(II) selenide – PbSe; Lead(II) sulfide – PbS; Lead(II) telluride – PbTe; Lead(II) thiocyanate – Pb(CNS) 2; Lead(II,IV) oxide – Pb 3 O 4; Lead(IV ...
First, the sulfide concentrate is roasted in air to oxidize the lead sulfide: [202] 2 PbS(s) + 3 O 2 (g) → 2 PbO(s) + 2 SO 2 (g)↑. As the original concentrate was not pure lead sulfide, roasting yields not only the desired lead(II) oxide, but a mixture of oxides, sulfates, and silicates of lead and of the other metals contained in the ore ...
Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. ... The usual lead ore is galena (lead(II) sulfide).
