In ancient Egypt, women used the stibic stone (antimony sulfide) as make-up for eyes. Follow Us: Company Registration: US DUNS Number: 07-930-0068. Antimony acts as an oxidizing agent and readily reacts with many metals to form antimonides. Antimony can be toxic depending on its chemical state. iUniverse
The structural properties of antimony and its compounds make it suitable for use in a variety of other industrial and commercial applications. Greenwood Publishing Group
It can also cause stomach pain, vomiting and ulcers. Breathing 2 mg/m3 of antimony for a long time can cause problems with the lungs (pneumoconiosis) heart problems (altered electrocardiograms), stomach pain, diarrhoea, vomiting and stomach ulcers. The oxidation of antimony (III) in soils was studied using X-ray absorption fine structure (XAFS) spectra. Of these, two are stable and found naturally in the percentages shown: 121Sb (57.36%) and 123Sb (42.64%). Exposure to 9 milligrams per cubic meter of air (mg/m3) of antimony as stibnite for a long time can irritate your eyes, skin, and lungs. Madrid et al., 1998. They’re Already Here, Unlimited Energy: Let’s Build a Mini Sun…, What Science Issues President Trump Did — and Did Not — Address in This Year’s State of the Union. Biringuccio describes antimony sulfide as either "a monstrosity among metals" or, alternatively, "a material that is about to reach metallic perfection, but is hindered from doing so by being mined too soon". Antimony's electrical and thermal conductivity are lower than most metals' conductivities. It is thus able to form covalent bonding and exhibits -3 and +3 oxidation states (Haynes, 2015). (4)
Antimony is used in the semiconductor industry as an n-type dopant for silicon. email@example.com. Hug, B. Wehrli, C.A. Its unique chemical properties make it ideal for use as a vermillion pigment and certain other pigment shades such as orange and yellow, which are formed by slow oxidation of the sulfide. Instead, it occurs as a compound in more than 100 different minerals. A highly pure form of antimony is used to make different types of semiconductor devices such as infrared detectors and diodes. In the world economy, antimony is an important commercial element. The most common minerals containing antimony are stibnite, bournonite, tetrahedrite, jamesonite and boulangerite. Alloys of antimony and lead are used to manufacture batteries, cable sheatings, bullets and other products such as glass and paints. The halogens and sulphur can easily oxidize antimony when heated (Emsley, 2011). Electrolytic deposition of antimony results in an unstable, amorphous form of the element called explosive antimony. Russia and China are the leading producers of antimony. (2011). Parasitology Research 88 (5): 395–7. Antimony was discovered as an element in the 17th century although it had been in use several centuries earlier. Dover Publications
It is readily oxidized by air at normal conditions to form water and antimony trioxide (Krebs, 2006). (8)
This is a clear description of the element antimony. Reluctance of this element to engage in hybridization results in typical bond angles approximating 90 degrees.  a.ii. Source for Antimony Pentoxide, Flame Retardant, Oxide here. Sb2O3 Figure out how many moles you have of antimony and oxygen.. 51.5 g Sb * 1 mol/ 121.76 g= 0.43 moles Sb 16.9 g O * 1 mol/ 16 g= 1.06 moles O I don't think even in the simplest form, the masses of the elements given are … (5) Antimony is toxic and immediately dangerous to life or health at 50 mg m-3 or above.
Existence of antimony has been known since ancient times and was used by ancient alchemists to make other metals, beauty products, and concoctions for healing. Markscheme +3; Do not accept 3, 3+ or the use of Roman numerals. The compound is formed by the reactive effect of acids on antimony alloys or metal antimonides, electrolysis of basic or acidic solutions where antimony is used as a cathode, or reduction of antimony compounds. It is also alloyed with lead to make the latter more durable. (2)
This work is an experimental and theoretical study of antimony speciation and the solubility of Sb2O5, Sb2O3 and Sb2(SO4)3 at 298 K in aqueous sulphuric acid solutions (0 to 6 kmol/m3). - Sb Flame proofing materials, glass, ceramic enamels and pottery ( Harder, 2002 ) cnd [ ].
