Formula: CH 2 (COOH)C (OH) (COOH)CH 2 COOH citric acid lactic acid tartaric acid It is extracted from citrus fruits or made by fermenting molasses and is an intermediate in carbohydrate metabolism. Hydrated sodium hypophosphite, NaH2PO2×H2O, is used as an industrial reducing agent, particularly for the electroless plating of nickel onto metals and nonmetals. Pure hypophosphorous acid forms white crystals that melt at 26.5° C. The electronic structure of hypophosphorous acid is such that it has only one hydrogen atom bound to oxygen, and thus it is a monoprotic oxyacid. 1920 Martigny / Switzerland New York, NY 10018 USA (S.F.). Hypophosphorous acid. The alcohol and ether are removed by distillation (atomistry.com, 2008-2012). HPA has a density of 1.49 g/ml in its solid state and 1.22 g/ml in aqueous solution at 50% concentration. Lambertville, NJ 08530 One of the most common uses of phosphoric acid is for the removal of rust from metal surfaces. It is used as an esterification catalyst. Application news, practical tips for the laboratory, and more. The appearance of its liquid form can be seen in Figure 2. Wills, H. (1858). These can be eliminated by the addition of alcohol and ether to the evaporated solution, when the salts are precipitated. This acid in its commercial form contains calcium salts. D Metaphosphoric acid. Phosphinic acid EC Number: 228-601-5 EC Name: Phosphinic acid CAS Number: 6303-21-5 Molecular formula: H3O2P IUPAC Name: phosphinic acid . Find Hypophosphoric acid 50% from China Manufacturer, Manufactory, Factory and Supplier - Jinan Shijitongda Chemical Co., Ltd. on ECVV.com The damage depends on the length of exposure, but it can attack the cornea and cause blindness. Retrieved from ChemSpider. HPA is corrosive to skin and eyes. HPA is also used as a bleaching or decolourizing agent for plastics, synthetic fibres, and chemical products. If you continue to use this site we will assume that you are happy with it. It is widely used as a reducing agent, Ag, Cu, Ni, Hg, and other metals are reduced to the corresponding metal for the verification of As, Nb, Ta, and other reagents (ChemicalBook, 2016). It acts as a rust converter on direct application to rusted iron, steel, and other metal surfaces. Hypophosphorous acid is used as a reducing agent in electroless nickel plating. The pure acid can be obtained by extraction of its aqueous solution by diethyl ether. If it is spilled on clothes, remove immediately and wash with water. What Are The Natural Resources in Argentina?
