As is toxic to both plants and animals. Se, despite being an essential micronutrient for animal nutrition, is potentially toxic because the concentra­ tion range between deficiency and toxicity in animals is narrow. Seleniferous soils release enough Se to produce vegetation toxic to grazing animals. Such soils occur in the semiarid states of the western United

    NANO3D SYSTEMS LLC 1110 NE Circle Blvd., ATAMI/Bldg. 11, Corvallis, Oregon 97330-4254 T 503-927-4766| F 541-758-9320| http://www.nano3dsystems.com Arsenic (As33) Properties Arsenic is a silvery-white metalloid with an atomic mass of 74.92 u. As has a density of 5.73 g/cm3, a melting point of 814 oC, and a Brinell hardness of 1440 MPa. The most common compounds have As in the +3 and +5 states, while it also exists in other oxidation states such as -3, -2, -1, +1, +2, +4. Its standard electrode potential in respect to As+3 is +0.3V. Though stable in dry air, arsenic forms a golden-bronze tarnish upon exposure to humidity which eventually becomes a black surface layer. Arsenic makes arsenic acid with concentrated nitric acid, arsenous acid with dilute nitric acid, and arsenic trioxide with concentrated sulfuric acid. It does not react with water, alkalis, or non-oxidizing acids. As is estimated to be at average concentration of 1.5 parts per million (ppm) in the Earth's crust. Plating Solutions Arsenic can be electrochemically deposited from aqueous electrolytes, containing in g/l: a) Example #1. Arsenic trioxide – 90, sodium hydroxide – 110 ml/l, potassium sodium tartrate tetrahydrate (Rochelle salt) - 80 with pH ~8 at temperature of 15-25 oC, current density of 10 – 20 mA/cm2 and current efficiency of ~100%. b) Example #2. Arsenic trioxide – 120, sodium cyanide – 3.7, sodium hydroxide – 120 at temperature of 15-25 oC and current density of 3 – 22 mA/cm2. Arsenic clectrodeposition can be also performed from choline chloride/ethylene glycol deep eutectic solvent [1].

  • Chapter 6.1 Arsenic
    Chapter 6.1 Arsenic General description Arsenic (As) and its compounds are ubiquitous in nature and exhibit both metallic and nonmetallic properties. The trivalent and pentavalent forms are the most common oxidation states. From both the biological and the toxicological points of view, arsenic compounds can be classified into three major groups: inorganic arsenic compounds; organic arsenic compounds; and arsine gas. The most common trivalent inorganic arsenic compounds are arsenic trioxide, sodium arsenite and arsenic trichloride. Pentavalent inorganic compounds include arsenic pentoxide, arsenic acid and arsenates, e.g. lead arsenate and calcium arsenate. Common organic arsenic compounds are arsanilic acid, methylarsonic acid, dimethylarsinic acid (cacodylic acid) and arsenobetaine. Arsenic trioxide is only slightly soluble in water; in sodium hydroxide it forms arsenite and with concentrated hydrochloric acid it forms arsenic trichloride. Sodium arsenite and sodium arsenate are highly soluble in water. Interchanges of valence state may occur in aqueous solutions, depending on the pH and on the presence of other substances which can be reduced or oxidized (1). Sources Arsenic appears in nature primarily in the form of sulfides in association with the sulfides of ores of silver, lead, copper, nickel, antimony, cobalt and iron. Trace amounts of arsenic are found in soils and other environmental media. Arsenic is mainly transported in the environment by water. In oxygenated water, arsenic usually occurs as arsenate, but under reducing conditions, for instance, in deep well-waters, arsenites predominate. In water, the methylation of inorganic arsenic to methyl- and dimethylarsenic acids is associated with biological activity. Some marine organisms have been shown to transform inorganic arsenic into more complex organic compounds, such as arsenobetaine, arsenocholine and arsoniumphospholipids.

  • Arsanilic Acid
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.
