Silver Nitrate Chemical Analysis

- Jul 21, 2017-

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

Of the important reagents, medically used as antivirus agents, Silver Nitrate 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, tissue and organogenesis, Silver Nitrate especially the glomerular basement membrane silver calm, can lead to thickening of the basement membrane.

Short-term excessive skin irritation and corrosive effect on the respiratory tract, bronchitis,

Skin silver calm, common hand, forearm and other exposed parts, Silver Nitrate showing gray and brown black spots, some people appear systemic skin silver calm, this silver calm change is often lasting, easy to subside, Silver Nitrate 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 black, if hydrogen sulfide, Silver Nitrate with or without light are black. Silver Nitrate Can be decomposed by heating and silver.

After taking the silver nitrate, can quickly inhalation of concentrated salt water, Silver Nitrate and 2% sodium chloride injection slowly gastric lavage, Silver Nitrate so that the formation of silver chloride precipitation, and to other symptomatic treatment. Skin and eye mucosal silver calm, 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, far organic matter and easy to oxidize the material at the preservation.

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 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. The aqueous solution and the ethanol solution were neutral to the litmus and had a pH of about 6. The boiling point of 444 ° C (decomposition). There is oxidation. In the presence of organic matter,Silver Nitrate see 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 disodium hydrogen phosphate reaction, Silver Nitrate the formation of yellow silver phosphate Ag3PO4 precipitation; reaction with halogen ions, Silver Nitrate Forming a 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 can react with NH3, CN-, SCN- and so on to form various complex ions.
