Silver nitrate poisoning

Many silver compounds are unstable to light, and are thus shipped ia brown glass or opaque plastic bottles. Silver compounds that are oxidants, eg, silver nitrate and iodate, must be so identified according to U.S. Department of Transportation (DOT) regulations. Compounds such as silver cyanide, which is toxic owiag to its cyanide content, must carry a poison label. However, most silver compounds are essentially nontoxic. 

All water-soluble silver salts are toxic and ingestion can cause severe poisoning (see Silver Nitrate). Silver is listed by the US EPA as one of the priority pollutant metals in the environment.

The solution containing the arsenic compound is then added in small amounts at a time to the contents of the flask. If much arsenic is present, there will be an almost immediate blackening of the silver nitrate solution. Disconnect the rubber tube at C. Heat the tube at A to just below the softening point a mirror of arsenic is deposited in the cooler, less constricted portion of the tube. A second flame may be applied at B to ensure complete decomposition (arsine is extremely poisonous). When a satisfactory mirror has been obtained, remove the flames at A and B and apply a light at C. Hold a cold porcelain dish in the flame, and test the solubility of the black or brownish deposit in sodium hypochlorite solution. 

Exposure to silver nitrate by inhalation cause deleterious effects to tissues of the mucous membranes and upper respiratory tract. The symptoms of poisoning include but are not restricted to burning sensations, coughing,... 

ACGIH TLV TWA 0.6 ppm SAFETY PROFILE A poison by ingestion. Moderately toxic by inhalation, skin contact, and subcutaneous routes. Mutation data reported. Used as an antiseptic, disinfectant on superficial wounds, and in female reproductive tract. 1 1 mixtures with hexamethylenetetramine explode at 178°C. Incompatible with mercuric oxide, calomel, silver nitrate, tannin, balsam Peru directiy mixed, Li, acetone. When heated to decomposition it emits toxic fumes of T. 

A strong base. Vigorous reaction with 1,2,4,5-tetrachlorobenzene has caused many industrial explosions and forms the extremely toxic 2,3,7,8-tetrachlorodibenzodioxin. Mixmres with aluminum + arsenic compounds form the poisonous gas arsine. Potentially explosive reaction with bromine, 4-chlorobutyronitrile, 4-chloro-2-methylphenol (in storage), nitrobenzene + heat, sodium tetrahydroborate, 2,2,2-trichloroethanol, zirconium + heat. Reacts to form explosive products with ammonia + silver nitrate (forms silver nitride), N,N -bis(trinitroethyl)urea (in storage), cyanogen... 

SAFETY PROFILE Experimental poison by subcutaneous route. Moderately toxic to humans by ingestion. Moderately toxic experimentally by ingestion, intraperitoneal, and intravenous routes. An experimental teratogen. Human systemic effects by multiple and unspecified routes toxic psychosis, excitement, respiratory stimulation, nausea or vomiting, and sweating. Experimental reproductive effects. Mutation data reported. A powerful irritant which affects the central nervous system. Incompatible with ferric salts, mineral acids, iodine, lead acetate, silver nitrate, sodium phosphate powder. When heated to decomposition it emits toxic fumes of Na20. 

CjHjCljOj Noncombustible solid. Reacts with strong bases, amines, amides, inorganic hydroxides alkalis, alkaline earth metals alkali carbonates ammoniacal silver nitrate strong oxidizers soluble barbiturates producing chloroform and formate. Incompatible with camphor, menthol, or thymol. Contact with hydroxylamine produces poisonous hydrogen cyanide gas. Attacks metals in the presence of moisture. In heat of decomposition or fire, releases hydrogen chloride and other toxic fumes.
