Silver nitrate contains silver and nitrate, while the elemental silver has a valence of +1 and nitrate has a valence of -1, so the chemical formula is AgNO? Silver nitrate is a colorless transparent rhombohedral lamellar crystal, soluble in water and ammonia, soluble in ether and glycerol, slightly soluble in anhydrous ethanol, almost insoluble in concentrated nitric acid.

Chemical formula of silver nitrate

Silver nitrate contains silver and nitrate, and the elemental silver has a valence of +1 and nitrate has a valence of -1, so the chemical formula is AgNO?

Silver nitrate is a colorless transparent rhombohedral lamellar crystal, soluble in water and ammonia, soluble in ether and glycerol, 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 oxidizing property is strong and has a certain corrosive property, which is used in medicine to corrode the proliferated granulation tissue, and the dilute solution is used as a fungicide for eye infections. It is a light yellow liquid when melted and remains white when solidified.

Silver nitrate turns gray-black when it meets organic matter and decomposes into silver. Pure silver nitrate is light-stable, but because of the general lack of purity of the product, its aqueous solution and solid are often kept in brown reagent bottles. Silver nitrate decomposes into silver, nitrogen, oxygen and nitrogen dioxide when it is heated to 440°C. The silver decomposes into nitrogen, nitrogen, oxygen and nitrogen dioxide. Aqueous and ethanol solutions react neutrally to litmus at a pH of about 6. Boiling point 444°C (decomposition).

In the presence of organic matter, it turns gray or gray-black in the presence of light. Silver nitrate can react with a range of reagents by precipitation or coordination (see coordination compounds). For example, with hydrogen sulfide reaction, the formation of black silver sulfide Ag2S precipitate; and potassium chromate reaction, the formation of reddish brown silver chromate Ag2CrO4 precipitate. It can also react with alkali to form brown-black silver oxide Ag2O precipitate; and oxalate ion to form white silver oxalate Ag2C2O4 precipitate. Silver nitrate can react with NH3, CN-, SCN-, etc. to form various ligand molecules.

Silver nitrate is used in photographic emulsions, silver plating, mirror making, printing, medicine, hair dyeing, testing chlorine ions, bromine ions and iodine ions, etc. It is also used in the electronics industry.

What is silver nitrate

Silver nitrate, an inorganic compound with the chemical formula AgNO3, is a white crystalline powder, easily soluble in water, ammonia, glycerol, slightly soluble in ethanol. Pure silver nitrate is light stable, but because of the general lack of product purity, its aqueous solution and solid are often kept in brown reagent bottles. It is used in photographic emulsion, silver plating, mirror making, printing, medicine, hair dyeing, testing of chloride ions, bromide ions and iodide ions, etc. It is also used in the electronics industry.

Chemical Properties of Silver Nitrate

Silver nitrate turns gray-black when it meets organic matter and decomposes into silver. Pure silver nitrate is light stable, but because the general product is not pure enough, its aqueous solution and solid are often kept in brown reagent bottles. Silver nitrate decomposes into silver, nitrogen, oxygen and nitrogen dioxide when heated to 444 °C. Aqueous and ethanol solutions react neutrally to litmus with a pH of about 6. Boiling point 444°C (decomposition). Has oxidizing properties.

In the presence of organic matter, it turns gray or gray-black in the presence of light. Silver nitrate can precipitate or coordinate with a range of reagents. For example, with hydrogen sulfide reaction, the formation of black silver sulfide Ag2S precipitate; with potassium chromate reaction, the formation of reddish brown silver chromate Ag2CrO4 precipitate; with disodium hydrogen phosphate reaction, the formation of yellow silver phosphate Ag3PO4 precipitate; and halide ions reaction, the formation of silver halide AgX precipitate.

It can also react with alkali to form a brownish-black silver oxide Ag2O precipitate; and with oxalate ions to form a white silver oxalate Ag2C2O4 precipitate. Silver nitrate can react with NH3, CN-, SCN-, etc. to form various ligand molecules.
