Silver Nitrate (AgNO3) CAS 7761-88-8

Silver nitrate, with the chemical formula AgNO₃ and CAS No. 7761-88-8, is an inorganic silver salt widely used in analytical chemistry, electroplating, photography, electronics, and other industrial applications. It appears as white or colorless crystals and is readily soluble in water and ammonia.

As an important source of silver ions, silver nitrate is commonly used for chloride ion determination, silver plating, preparation of other silver compounds, photographic materials, and specialty chemical applications. It should be stored in a cool, dry, and light-protected place, away from organic materials and incompatible substances.

Product Description

Silver nitrate is an inorganic silver salt with the chemical formula AgNO₃ and a molecular weight of 169.87. It usually appears as white or colorless crystalline powder or crystals. Silver nitrate is highly soluble in water and ammonia, slightly soluble in methanol and ethanol, and insoluble in concentrated nitric acid.

Silver nitrate is chemically reactive. In aqueous solution, it is weakly acidic and can react with hydrogen sulfide to form black silver sulfide. It also reacts with halide ions to form silver halides, with strong alkalis to form silver oxide, and with potassium chromate to form reddish-brown silver chromate. Silver ions in silver nitrate solution can be reduced by metals such as zinc or copper, and may also be reduced by sodium sulfite or hydrazine hydrate.

Pure dry silver nitrate is relatively stable when protected from light. However, moist silver nitrate and its aqueous solution may decompose when exposed to light. In the presence of organic matter, silver nitrate can be reduced to metallic silver. When heated to about 444 °C, silver nitrate decomposes to form metallic silver and releases nitrogen oxides.

Applications

Silver nitrate is widely used in analytical chemistry, electroplating, electronics, photography, battery production, medicine, and other industrial applications.

In analytical chemistry, silver nitrate is commonly used for the detection and determination of chloride, bromide, iodide, cyanide, and thiocyanate ions. It is also used as a reference reagent for the standardization of sodium chloride solutions.

In the inorganic chemical industry, silver nitrate is used as an important raw material for producing other silver compounds. In the electronics industry, it can be used in conductive adhesives, specialty purification materials, and other electronic applications.

In the photosensitive materials industry, silver nitrate is used in the production of photographic films, X-ray films, and other light-sensitive materials. In the electroplating industry, it is widely used as a silver ion source for silver plating of electronic components, mirrors, decorative items, and industrial parts.

Silver nitrate is also used in silver-zinc batteries, ceramic coloring, laboratory reagents, and certain medical or daily chemical applications. In silver plating solutions, the concentration of silver nitrate can affect conductivity, throwing power, and deposition rate. Typical usage levels may vary depending on the specific plating formulation and process requirements.
