Q27109021. It is a black to red-black solid that is classified as a II-VI semiconductor of the n-type.
It is a colorless compound. Hydrogen selenide is a colorless gas that dissolves in water to make an acidic solution. Answer e. Ba 3 (PO 4) 2. Selenophosphate is the selenium donor used to synthesize selenocysteine, which is co-translationally incorporated into selenoproteins at in-frame UGA codons.
Some selenides are reactive to oxidation by air. Answer c. Al 2 O 3. 1 In nature, it occurs as mineral berzelianite. Much of the current research on cadmium selenide is focused on its nanoparticles.
Selenide ores are the source of selenium. Zinc selenide crystal optic disc, 25mm x 2mm, polished both sides
selenide(2-) Selenium, ion (Se2+) SE-2. [provided by RefSeq, Sep 2010] Cadmium selenide is an inorganic compound with the formula CdSe. Similar to sulfide, in aqueous solution, the selenide ion, Se2−, is prevalent only in very basic conditions. Al 2 Se 3 + (3 + x)H 2 O → 3H 2 Se + Al 2 O 3.xH 2 O Properties. In A selenide is a chemical compound containing a selenium anion with oxidation number of −2 (Se ), much as sulfur does in a sulfide. The selenide iodides are chemical compounds that contain both selenide ions (Se 2−) and iodide ions (I −) and one or metal atoms. Answer b (NH 4) 3 PO 4. % Se and ~53 at. SeZn. Structure, properties, spectra, suppliers and links for: Potassium selenide, 1312-74-9. For each of the following pairs of ions, write the symbol for the formula of the compound they will form: (a) K +, O 2− (b) \(\ce{NH4+}\), \(\ce{PO4^3-}\) (c) Al 3+, O 2− (d) Na +, \(\ce{CO3^2-}\) (e) Ba 2+, \(\ce{PO4^3-}\) Answer a. K 2 O. selenide. Zinc selenide (ZnSe) MFCD00011296. Its chemical formula is Se 2–. The formula for magnesium selenide is MgSe. selenide ion.
Cesium Selenide is generally immediately available in most volumes. Selenides are reducing agents when pure. Inorg. Its chemical formula is H 2 Se. 195-219.Thompson, D.; Boudjouk, P. A :Convenient Synthesis of Alkali Metal Selenides and Diselenides in Tetrahydrofuran and the Reactivity Differences Exhibited By These Salts Toward Organic Bromides" Journal of Organic Chemistry 1988, volume 53, pp. Selenide is an ion. The selenide ion is unstable except in very basic conditions. 2 Copper selenide may be prepared galvanically by coupled copper metal oxidation and Se reduction in alkaline selenosulfate (Na 2 SeSO 3).. We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. In neutral conditions, hydrogen selenide ion, HSe , is most common. General description Copper selenide is an ionic conductor. 8989AF. Some selenides are reactive to oxidation by air. Owing to the greater reducing power of selenide, metal selenides are more easily decomposed to the elements than are,Polyselenide anions are chains with the composition,The structures of polyselenides have been examined by.Polyselenides are prone to decomposition on exposure to air, in which case they are oxidized back to elemental selenium.Quantum dots based on metal selenides have been extensively for their distinctive spectral properties.Bernd E. Langner "Selenium and Selenium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim.Kolis, J.
