10. STABILITY AND REACTIVITY
Reactivity
No further relevant information available.
Chemical stability
Stable at room temperature in closed containers under normal storage and handling conditions. Light sensitive. Darkens on exposure to light.
Possibility of hazardous reactions
Reacts with acetylene in presence of ammonia to form silver acetylide, a sensitive powerful detonator when dry. In the absence of ammonia, or when calcium acetylide is added to a silver nitrate soln, explosive double salts of silver acetylide and silver nitrate are produced. Mercurous acetylide precipitates silver acetylide from aqueous nitrate. Reaction with chlorosulfonic acid is violent with nitrosulfonic acid being formed. Reduced by hydrogen sulfide in the dark. Easily reduced to metallic silver by ferrous salts, arsenites, hypophosphites, tartrates, sugars, tannins, volatile oils. Dry powdered magnesium and silver nitrate may ignite explosively on contact with a drop of water. Reaction with ammonium hydroxide, sodium hydroxide and stirring may be explosive. Reaction with phosphorus, or sulphur, and shock may be violently explosive. Reaction with charcoal and shock may result in ignition. Highly sensitive explosive is formed when calcium carbide is added to silver nitrate solution. Reaction with alcohols may form an explosive fulminate. When purified phosphine was passed rapidly into a concentrated solution of silver nitrate an explosion occurred.
Conditions to avoid
Heat, flame, sources of ignition, light, contamination and incompatible materials.
Incompatible materials
Reducing agents, combustible materials, organic materials, easily oxidised materials, acetylene + ammonia, acetylidene, alcohols, aldehydes, alkalis, alkali hydroxides, ammonia, ammonium compounds, antimony salts, arsenites, benzalkonium chloride, bromides, carbonates, carbides, charcoal, chlorides, chlorosulfonic acid, creosote, ferrous salts, halogenated acids and their salts, hydrazine and derivatives, hydrogen peroxide, hydrogen sulfide, hypophosphites, iodides, magnesium in powder form (with water), morphine salts, nitriles, non-metals, oils, organic nitro compounds, phosphates, sodium hydroxide, sugars, tannic acid, tannins, tartrates, thimerosal, thiocyanates, vegetable decoctions, and extracts, volatile oils.

11. TOXICOLOGICAL INFORMATION
Acute effects
No further relevant information available.
Eye contact
Corrosive. Can cause blurred vision, redness, pain, severe tissue burns and eye damage.
Skin contact
Corrosive. Symptoms of redness, pain, and severe burn can occur.
Ingestion
Corrosive. Swallowing can cause severe burns of the mouth, throat, stomach and gastrointestinal tract.Can cause sore throat, vomiting, diarrhoea. Poison. Symptoms include pain and burning in the mouth, blackening of the skin and mucous membranes, throat, and abdomen, salivation, vomiting of black material, diarrhoea, collapse, shock, coma and death. Ingestion of soluble silver salts may cause argyria, characterised by permanent blue-gray pigmentation of the skin, mucous membranes, and eyes. Lethal dose for humans is 2 grams, or about 28.6 mg/kg.
Inhalation
Extremely destructive to tissues of the mucous membranes and upper respiratory tract. Symptoms may include severe irritation, burning sensation, coughing, wheezing, laryngitis, shortness of breath, breathing difficulty, headache, nausea, vomiting and possible coma. May be absorbed into the body following inhalation with symptoms paralleling those from ingestion exposure. Dust deposits in the lungs may resemble a form of pneumoconiosis. Inhalation of silver metal dust and fume or of soluble silver compounds may eventually cause argyria, an unsightly blue-gray discolouration of the skin and mucous membranes, including gum tissue and conjunctiva of the eyes.
Toxicity and irritation
Nitrate or nitrite (ingested) under conditions that result in endogenous nitrosation are evaluated in the IARC Monographs (Vol. 94; in preparation) as Group 2A: Probably carcinogenic to humans.Carcinogenicity Evidence of reproductive effects.May cause methemoglobinemia, which is characterised by chocolate-brown coloured blood, headache, weakness, dizziness, breath shortness, cyanosis (bluish skin due to deficient oxygenation of blood), rapid heart rate, unconsciousness and possible death. Repeated inhalation may cause lung disease. Chronic inhalation or ingestion of silver salts may cause argyria characterised by a permanent blue-gray discolouration of the eyes, skin, mucous membranes, and internal organs. This malady results from the accumulation of silver in the body.Laboratory experiments have shown mutagenic effects.
