Molybdic Acid is an inorganic compound with a molecular formula of H2MoO4. Refers to the hydrated form of molybdenum trioxide and related substances. It is usually in the form of hydrate MoO3 · 2H2O, with a molecular weight of 179.97. It is a white or slightly yellow monoclinic columnar crystal or powder. Industrial products generally contain a small amount of Ammonium Molybdate, with a relative density of 3.124 (14°C). When dried in sulfuric acid or heated to 65~70℃, it loses crystal water and becomes anhydrous. Burned into molybdenum trioxide. Slightly soluble in water or strong acid. Soluble in alkaline solution, ammonia water, alkali metal carbonate solution and hydrogen peroxide solution. It exists in the form of molybdate in alkaline solution and ammonia water. It exists in the form of molybdate in strong acid solution. When the acidity increases, (MoO4)2- ions in the solution are prone to generate bimolybdate ions (Mo2O72-)n and homopolyacid ions, such as (Mo7O24)6-, (Mo8O26)4-, (Mo36O112)8- and so on. It is stable at room temperature, and the dark blue molybdenum blue can be obtained by treating the suspension of molybdic acid with reducing agents such as hydrogen sulfide, sulfur dioxide and zinc. Ammonium molybdate is obtained by oxidizing and roasting molybdenite sand with ammonia water, and then acidifying with nitric acid to obtain ammonium molybdate. Used in the manufacture of molybdenum-containing catalysts, molybdenum salts, molybdenum trioxide, Molybdenum Powder, ceramic glazes, blue pigments, coatings, medicines, etc. Molybdic Acid,High-Purity Molybdic Acid,Chemical Reagent Molybdic Acid,Molybdic Acid Dihydrate Jiangsu Lucky Metal Materials Co., Ltd. , https://www.luckymetalmoly.com
