English Name: Hydrogen Chloride
CAS No.: 7647-01-0
Molecular formula: ClH
Molecular weight: 36.46090
Purpose:
Preparation of various compounds: the preparation of inorganic compounds is also a kind of industrial hydrochloric acid, which can produce acid-base phenomenon, so many inorganic compounds can be prepared. For example, the chemicals used in water treatment are ferric chloride and polyaluminium chloride. Ferric chloride and polychloride have the function of flocculant and coagulant in the fields of production sewage treatment and drinking water.
Production of various inorganic substances: industrial hydrochloric acid can also produce other inorganic substances, including calcium chloride salt, nickel chloride salt for electroplating, battery production, etc. activated carbon is usually prepared from charcoal by zinc chloride activation method.
Control pH value: industrial hydrochloric acid can control the pH value of the solution. When the purity requirement is very high in industry, high-purity hydrochloric acid is often used to adjust the pH value of water flow. When the purity requirement of industry is relatively low, industrial pure hydrochloric acid can meet the requirements of neutralizing wastewater or treating water in swimming pool.
Test flame reaction: industrial hydrochloric acid will also be used to test metals or their compounds. Flame reaction is often used. It is used to clean the platinum wire with dilute hydrochloric acid to remove the influence of impurity elements. Before testing the substance, the platinum wire should be cleaned with hydrochloric acid, and then burned on the flame until the flame shows the original color.
