India GST: … Antimony is one of the numerous elements that occur naturally in the environment, although it is found mainly in compound form. Antimony also has the unusual property that (like water) it expands as it freezes.  b.i. Arab alchemist Abu Musa Jabir Ibn Hayyan (721–815 CE) probably first called it antimony — ‘anti’ meaning not and ‘monos’ meaning alone because the element does not occur alone in nature (Shotyk, Krachler & Chen, 2006). (1) Identify which reactants are being oxidized (the oxidation number increases when it reacts) and which are being reduced (the oxidation number goes down). Deduce the chemical equations for these two reactions. The modified Gutzeit method can be used to determine small amounts of antimony (Harder, 2002). It's likely that Roman author Pliny gave it the name stibium, from which the modern element symbol Sb was taken, in the first century AD. It is found in nature as the minerals valentinite and senarmontite. Carefully, insert coefficients, if necessary, to make the numbers of oxidized and reduced atoms equal on the two sides of each redox couples. It always occurs in hydrated form, Sb2O5-nH2O. Antimony acts as an oxidizing agent and readily reacts with many metals to form antimonides. With time, stibine decomposes into hydrogen and metallic antimony. Two of these radioactive isotopes (antimony-124 and antimony-125) are used commercially as tracers (Emsley, 2011). 2. Possible oxidation states are +3,5/-3. Pure antimony (purity level exceeding 99.999%) is applied in semi-conductor technology. Thus, antimony’s double bond arrangement is described as singly bonded with localized negative charges (Harder, 2002). Nature’s Building Blocks: An A-Z Guide to the Elements.  a.i. 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. 3. Four other elements expand when they freeze; silicon, bismuth, gallium and germanium. The metallic form is silvery, bright, brittle and hard while the non-metallic form is a grayish powder. The dominant cations species in the pH range unique to natural environments is Sb(OH)3 and Sb(OH)6¯ for trivalent antimony and pentavalent antimony respectively. email@example.com. Computational studies of antimony’s potential bonding arrangements suggest minimal d-orbital participation. Antimony metal is generally stable under normal conditions and does not react with air or water.

The abundance of antimony in the earth’s crust is estimated to be 0.2 parts per million, making it one of the rarest of the chemical elements found in the earth’s crust. In the first half of the 1500s, Vannoccio Biringuccio wrote a description "Concerning Antimony and Its Ore". Antimony can be toxic depending on its chemical state. Antimony is believed to have been named by Roman scholar Pliny (23–79 CE) who called it stibium. Antimony is a shiny, silvery white element. This was still not chemistry as we know it. Nuclear Physics 20: 220. 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. In his writings, Lémery describes how acids prick the tongue because they contain spiky particles, while metals dissolve in acids because the sharp points of acids tear the metal particles apart. Because it is semi metallic, it exists as both a metal and non-metal. Ancient Egyptians and Roman alchemists used antimony to prepare beauty products and drugs. Chemical Formula: a) Sb2O3. It is also alloyed with lead to make the latter more durable. In compounds of antimony (where known), the most common oxidation numbers of antimony are: 5, 3, and -3.

Such high levels of purity can be obtained from the reduction of high purity compounds such as chloride and trioxide with hydrogen. In addition to the usual form of antimony, there are two allotropes: yellow crystalline and amorphous black. Vannoccio Biringuccio, The Pirotechnia of Vannoccio Biringuccio, translated by Cyril Stanley Smith and Martha Teach Gnudi, (1990) p201. Complex ores such as livingstonite are also a major source of antimony. Like arsenic, which sits directly above it in the periodic table, the toxicity of antimony and its compounds varies according to the chemical state of the element. Antimony is mainly used metallurgically as an additive substance because its physical properties are not suitable for engineering. It also finds its way into the environment through numerous applications by human actions. He also warns against heating the antimony sulfide too strongly because this will produce a substance that "although this is very white and almost more shining than silver, it is much more brittle than glass." Antimony was discovered as an element in the 17th century although it had been in use several centuries earlier. (3) In an alternative process, the sulfide is converted to oxide and then weighed as Sb4O6. (1) It is likely that the Roman author Pliny used the name stibium in the first century AD. Antimony alloys are therefore used in making typefaces for clear, sharp printing. Emsley, J. Not so common is -3. Major Applications with all Structural and Functional Details.

Other antimony compounds are used to manufacture paints, flame proofing materials, glass, ceramic enamels and pottery (Harder, 2002). CrossRef View Record in Scopus Google Scholar. Both antimony and its compounds are highly toxic and thus dangerous to human health. Of these, two are stable and found naturally in the percentages shown: 121Sb (57.36%) and 123Sb (42.64%). This results from the fact that antimony is infrequently found native, but usually combined with sulfur or with heavier metals such as copper, lead and silver. Antimony is also used as an alloying constituent in tin to produce tin-based babbits and pewter for use in bearing metal applications. CRC Handbook of Chemistry and Physics. The flame is bluish white. These isotopes give off some form of radiation. Antimony is metalloid, so it has some metallic properties but not enough to be classified as a true metal. We get the modern element symbol for antimony, Sb, from the word stibium. People have been making use of antimony’s compounds for thousands of years. The higher the proportion of antimony in the alloy, the harder and more brittle it will be. Deduce one other common oxidation number exhibited by antimony in some of its compounds. An andosol soil sample and artificial soil samples (SiO 2 blended with iron (III) hydroxide and manganese (IV) oxide) were used herein. (2002).
