Hydrochloric acid is an important inorganic chemical raw material, widely used in dyes, pharmaceuticals, food, printing and dyeing, leather, metallurgy and other industries. Hydrochloric acid can be used in the manufacture of chloride and zinc chloride (zinc chloride is a flux), can also be used to extract ore from the radium, vanadium, tungsten, manganese and other metal nitrate AR 500ml, made chloride. A variety of purposes: 1, for example hydrometallurgical metals, tungsten smelting, first scheelite (calcium tungstate mineral) mixed with sodium carbonate to produce acid calcined in air (800 ℃ ~ 900 ℃) sodium. CaWO4 + Na2CO3 = Na2WO4 + CaO + CO2 ↑ The sintered compact was immersed in water 90 ℃, so that the price of analytically pure nitric acid dissolution of sodium tungstate, and adding hydrochloric acid, after the precipitated tungstic acid was filtered off, and then by burning, to generate tungsten oxide. Na2WO4 + 2HCl = H2WO4 ↓ + 2NaCl H2WO4 = WO3 + H2O ↑ Finally, tungsten oxide in a stream of hydrogen burning to obtain metallic tungsten. WO3 + 3H2 = W + 3H2O ↑ corrosive nitric acid cleaning is used as analytical, can be used in conjunction with hydrogen peroxide. Hydrochloric acid-based chemical cleaning agents has the effect of strong, fast, the effect is obvious, easy to use and low cost for carbon steel, copper, but not for austenitic stainless steel, titanium and other materials chemical cleaning.
