Silver nitrate is a kind of chemical products, mainly used in silver-plated, mirror, printing, medicine and other industries, silver nitrate has soluble in water characteristics, it has no color, Silver Nitrate high purity of silver nitrate for light reaction is relatively stable.
If the chloride ions, bromine ions, iodine ions, etc. Silver Nitrate will react to produce insoluble in water, insoluble in nitric acid silver chloride (white precipitate), silver bromide (light yellow precipitate), silver iodide (yellow precipitate) and so on. Therefore, it is often used to test the existence of chloride ions.
Soluble in ether and glycerin, slightly soluble in anhydrous ethanol, almost insoluble in concentrated nitric acid. Its aqueous solution is weakly acidic. Silver nitrate solution contains a large number of silver ions, so the oxidation is stronger, and there is a certain corrosive, Silver Nitrate medical use for the granulation tissue of corrosion hyperplasia, dilute solution for ocular infection of fungicides. After melting, the light yellow liquid is still white after solidification.
Silver nitrate is turned into silver when organic matter becomes gray and black. Pure silver nitrate is stable in light, but its aqueous solution and solids are often kept in a brown reagent bottle because of the general purity of the product. Silver nitrate is decomposed into silver, nitrogen, Silver Nitrate oxygen and nitrogen dioxide when heated to 440 ℃. Aqueous solution and ethanol solution have a neutral reaction to the litmus, the ph is about 6. Boiling point 444 ℃ (decomposition). Oxidizing. In the presence of organic matter, see light gray or gray-black. Silver nitrate can react with a series of reagents to precipitate reactions or coordination reactions (see coordination compounds). For example, with hydrogen sulfide reaction, the formation of black silver sulfide ag2s precipitation; reaction with potassium chromate, formation of red-brown chromium-acid silver Ag2cro4 precipitation; reaction with sodium dihydrogen phosphate, forming yellow silver phosphate ag3po4 precipitate; reaction with halogen ions, Silver Nitrate forming silver halide agx precipitate. Also can be with alkali action, form brown black oxidized silver ag2o precipitate, and oxalic acid root ion action form white oxalic acid silver Ag2c2o4 precipitate etc. Silver nitrate can react with NH3, CN and scn-to form various coordination ions.
Analytical chemistry is used to precipitate chloride ions, and the working standard of silver nitrate is used to calibrate sodium chloride solutions. The inorganic industry is used to make other silver salts. The electronic industry is used in the manufacture of conductive adhesives, Silver Nitrate new gas purifying agents, a8x molecular sieves, silver-plated and live-working gloves. Photosensitive industries are used to make photographic materials such as film films, X-ray photographic films and photographic films. Electroplating industry for electronic components and other crafts silver-plated, but also a large number of mirrors and vacuum flask gall bladder silver material. The battery industry is used for the production of silver zinc batteries. Silver Nitrate Medicine is used as bactericide and corrosive agent. The daily chemical industry is used to dye hair. Analytical chemistry is used to determine chlorine, bromine, iodine cyanide and thiocyanate.
