Silver Nitrate The Harm To The Human Body

- Oct 24, 2017 -

Silver nitrate is a colorless crystal, soluble in water. Pure silver nitrate is stable to light, but because of the general product purity is not enough, its aqueous solution and solid are often stored in the brown reagent bottle. For photographic emulsion, silver, mirror, printing, medicine, dyeing hair, test chloride, bromide and iodide, etc., also used in the electronics industry.

Analytical chemistry for the precipitation of chloride ions, the working standard of silver nitrate for calibration of sodium chloride solution. Inorganic industry for the manufacture of other silver salts. The electronics industry is used in the manufacture of conductive adhesives, new gas purifiers, A8x molecular sieves, silver-plated and gloved gloves. Photographic industry for the manufacture of film, x-ray film and photographic film and other photographic materials. The electroplating industry is used for silver plating of electronic components and other handicrafts, and is also used as a silver-plated material for mirrors and thermoses. The battery industry is used to produce silver-zinc batteries. Medicine used as a fungicide, corrosion agent. Japanese chemical industry for dyeing hair and so on. Analytical chemistry is used to determine chlorine, bromine, iodine cyanide and thiocyanate.

For non-cyanide silver, such as thio sulfuric acid silver plating, silver plating silver, silver imide disulfide silver, silver sulfosalic acid silver and other main salt. Is the source of silver ions. Silver nitrate content on the silver plating solution conductivity, dispersion and precipitation rate have a certain impact. The general dosage is 25-50g / L.

The aqueous solution of silver nitrate can be reduced by organic reductant aldehydes and sugars. So it is the reagent to test aldehydes and sugars. Also used to determine the chloride ion, the determination of manganese catalyst, electroplating, photography, porcelain coloring.

What are the hazards of silver nitrate to the human body?

Mainly silver ions are heavy metals, will be poisoned, in the hands will be white, mainly heavy metals caused by protein denaturation.

Silver nitrate is a colorless crystal, soluble in water. Pure silver nitrate is stable to light, but because of the general product purity is not enough, its aqueous solution and solid are often stored in the brown reagent bottle. For photographic emulsion, silver, mirror, printing, medicine, dyeing hair, test chloride, bromide and iodide, etc., also used in the electronics industry.

Silver nitrate in the case of organic matter gray black, decomposition of silver. Pure silver nitrate is stable to light, but because of the general product purity is not enough, its aqueous solution and solid are often stored in the brown reagent bottle. Silver nitrate is heated to 440 ° C to decompose into silver, nitrogen, oxygen and nitrogen dioxide. Aqueous solution and ethanol solution on the elixir neutral reaction, silver nitrate with a series of reagents precipitation reaction or coordination reaction. For example, with hydrogen sulfide reaction, the formation of black silver sulfide Ag2S precipitation; with potassium chromate reaction, the formation of reddish brown silver chromate Ag2CrO4 precipitation; with sodium hydrogen phosphate reaction, the formation of yellow silver phosphate Ag3PO4 precipitation; reaction with halogen ions, To form silver halide AgX precipitate. But also with the role of alkali, the formation of brown black silver oxide Ag2O precipitation; with the role of oxalate ions to form white silver oxalate Ag2C2O4 precipitation. Silver nitrate can react with NH3, CN-, SCN- and so on to form various coordination ions.
