Colorless, tasteless transparent crystal or white crystal, Silver Nitrate bitter taste. Density: 4.35, melting point 212 ° C, boiling point: 440 ° C. Used for photography, mirrors, Silver Nitrate silver plated, hidden and non-fading inks, stains, porcelain, coloring, etching ivory and chemical analysis
Important agents, Silver Nitrate medically used as antivirus agents, astringents, neonatal ophthalmic prophylaxis and veterinary use as wound and local inflammatory treatment.
Animal test can lead to hemolytic anemia and pulmonary edema, Silver Nitrate repeated small doses of silver injection, can cause anemia, myeloproliferation, Silver Nitrate tissue and organogenesis, especially the glomerular basement membrane of silver calm, can lead to thickening of the basement membrane.
Short-term overdose on the skin and mucous membranes have a stimulating effect and corrosion, the respiratory tract damage to bronchitis, Silver Nitrate respiratory submucosal silver calm, silver calm first appeared in the conjunctiva, after taking silver nitrate digestive tract mucous membrane is corrosive.
Skin silver calm, Silver Nitrate common hand, forearm and other exposed parts, showing gray and brown black spots, some people appear systemic skin silver calm, Silver Nitrate this silver calm change is often lasting, easy to subside, the impact on the respiratory system can lead to Chronic bronchitis
Silver nitrate is a strong oxidizing agent and is at risk of fire. When the fire is on fire.
And organic matter coexistence with the case of light can be black, Silver Nitrate if hydrogen sulfide, with or without light are black. Can be decomposed by heating and silver.
Skin: Wear protective clothing to avoid skin contact.
Eyes: with chemical safety goggles.
Inhalation: Must be equipped with respirator to prevent excessive intake of silver nitrate dust or its mixture.
After taking the silver nitrate, Silver Nitrate can quickly inhalation of concentrated salt water, and 2% sodium chloride injection slowly gastric lavage, so that the formation of silver chloride precipitation, and to other symptomatic treatment. Skin and eye mucosal silver calm disease, Silver Nitrate can be used sodium thiosulfate and potassium ferricyanide mixture, local intradermal or subconjunctival injection, have a certain effect.
In order to prevent the decomposition of silver nitrate, Silver Nitrate can be stored in brown bottles or dark containers, in the low temperature, ventilation, Silver Nitrate far organic matter and easy to oxidize the material at the preservation. Method: (II) class.
Occurrence of leakage, should wear protective masks and gloves. Rinse with water, dilute the sewage
Silver nitrate in the case of organic matter gray black, Silver Nitrate decomposition of silver. Pure silver nitrate is stable to light, but because of the lack of purity of the product in general, its aqueous solution and solids are often kept in brown reagent bottles. Silver nitrate is heated to 440 ° C to decompose into silver, nitrogen, oxygen and nitrogen dioxide. The aqueous solution and the ethanol solution were neutral to the litmus and the pH was about 6. The boiling point of 444 ° C (decomposition). There is oxidation. In the presence of organic matter, see the light becomes gray or grayish black. Silver nitrate reacts with a series of reagents for precipitation or coordination (see coordination compounds). For example, with hydrogen sulfide reaction, Silver Nitrate 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. Silver Nitrate 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 and NH3, CN-, SCN- and other reactions, the formation of a variety of ions.
