Sulfite has an oxidation number of -2 and only one is required, since mercury has an oxidation number of +2. Objects that emit radiation in these wavelengths still have to be quite hot—several hundred degrees Celsius—but not as hot as those detectable by uncooled sensors. [12] As an infrared detector, PbS functions as a photon detector, responding directly to the photons of radiation, as opposed to thermal detectors, which respond to a change in detector element temperature caused by the radiation. Lead(II) sulfide [PbS] MENU: Periodic table Solubility Table Game News About на русском SOLUBILITY: water [H 2 O]: 0,000068 (25°) PROPERTIES: grey-black cubic crystals M (molar mass): 239,300 g/mol MP (melting point): 1077 °C MB (boiling point): 1281 °C D (density): 7,59 (20°, g/cm 3 , s.) NACRES NA.23 [5] In fact, lead sulfide was one of the earliest materials to be used as a semiconductor. Copyright for NIST Standard Reference Data is governed by This reaction is used in qualitative inorganic analysis. Standard Reference Data Act. Laboratoriya znaniy, 2008. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. Galena is the principal ore and the most important compound of lead. Galena is the principal ore and the most important compound of lead. ) in formulas for adduct molecules, such as water of hydration. This site explains how to find molar mass. of a chemical compound, More information on the A major process involves smelting of PbS followed by reduction of the resulting oxide.

The reaction of lead (II) sulfide {eq}\rm PbS {/eq} and oxygen gas {eq}\rm O_2 {/eq} to produce lead (II) oxide {eq}\rm PbO {/eq} and sulfur dioxide {eq}\rm SO_2 {/eq} is: Although of little commercial value, PbS is one of the oldest and most common detection element materials in various infrared detectors. Idealized equations for these two steps are:[7]. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. common chemical compounds. Answer. (Other compounds used for this purpose include indium antimonide (InSb) and mercury-cadmium telluride (HgCdTe), which have somewhat better properties for detecting the longer IR wavelengths.) – P. 1408 • Grinvud N., Ernsho A. Himiya elementov. Submit Answer Retry Entire Group 8 more group attempts remaining fullscreen. Chemical formulas are case-sensitive. Measuring the resistance change is the more commonly used method. 3. Calculate the molecular weight © 2018 by the U.S. Secretary of Commerce PubChem Substance ID 24858620. These relative weights computed from the chemical equation are sometimes called equation weights. - T.1. CopyCopied, XCAUINMIESBTBL-UHFFFAOYSA-N What is the formula of lead II sulfite? moles. on behalf of the United States of America. PBSO3 Linear Formula PbSO 4. Cooling the PbS elements, for example using liquid nitrogen or a Peltier element system, shifts its sensitivity range to between approximately 2 and 4 μm. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Lead sulfide-containing nanoparticle and quantum dots have been well studied. Physical Form: White Powder: Key Words: PbSO3 : Vendors: Available Properties; Molecular Weight; Heat of Formation, Crystal : Property Data; This page displays only the text of a material data sheet. Convert grams Lead(II) Sulfite to moles or moles Lead(II) Sulfite to grams, Molecular weight calculation: Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid or by treating a soluble lead salt with sulfuric acid. Lead (II) sulfide is formed naturally from other lead compounds in reducing environments when sulfur is available. Material Notes: CAS Number: 7446-10-8. [14] Lead sulfide is insoluble and a stable compound in the pH of blood and so is probably one of the less toxic forms of lead. The sulfur dioxide is converted to sulfuric acid. If this is the case, it would be the first time the substance was identified on a foreign planet. Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid or by treating a soluble lead salt with sulfuric acid. Note that rounding errors may occur, so always check the results. PbSO3. ››Lead(II) Sulfite molecular weight. Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula PbS. – P. 95. Mass percentage of the elements in the composition. and Informatics, X-ray Photoelectron Spectroscopy Database, version 4.1. "PbS" redirects here. [15] A large safety risk occurs in the synthesis of PbS using lead carboxylates, as they are particularly soluble and can cause negative physiological conditions. Element Symbol Atomic Mass Number of Atoms Mass Percent; Plumbum: Pb: 207.2: 1: 72.129%: Sulfur: S: 32.065: 1: 11.163%: Oxygenium: O: 15.9994: 3: 16.709%: Notes on using the Molar Mass Calculator. star. Finding molar mass starts with units of grams per mole (g/mol). 1 Rating. Soluble in HNO3, hot HCl, Soluble in strong HNO3, in excess of hot HCl, Inorganic Compound; Lead Compound; Pollutant; Household Toxin; Industrial/Workplace Toxin; Natural Compound. [8] Traditionally, such materials are produced by combining lead salts with a variety of sulfide sources. Since PbS is the main ore of lead, much effort has focused on its conversion. Lead (II) sulfite has the formula of PbSO3. [9][10] PbS nanoparticles have been recently examined for use in solar cells.[11]. Want to see the step-by-step answer? Toxicology. 15 16 17. Lead sulfate is toxic by inhalation, ingestion and skin contact. Molecular Formula PbS; Average mass 239.265 Da; Monoisotopic mass 239.948669 Da; ChemSpider ID 14135 Data from NIST Standard Reference Database 69: NIST Chemistry WebBook; The National Institute of Standards and Technology (NIST) uses its best efforts … Finding the atomic masses of elements in the periodic table.
