Silver Nitrate

Silver Nitrate

Silver nitrate used for making negative of taking pictures, vacuum flask refill and mirror manufacture, but also uses in silver plating, printing, corrosive agent in medicine, hair dye, analytical agent, preparation of other silver salt and colorfast ink.

Product details

Product titles: Silver Nitrate

Product Description

Silver nitrate binds to selective amino acid residues under weakly acidic or neutral pH conditions making it suitable as a stain for identification of proteins. Silver nitrate is also utilized in the staining of nucleic acids and glycoconjugates in gels. Silver nitrate is a source of silver ions in biological studies, such as in toxicological investigations on yeast and marine animals. This product has been shown to induce the protein conformational condition of amyloid A amyloidosis in mice. Silver nitrate also has powerful germicidal activity. It is far less sensitive to light than the halides.

Product Information

 

Silver nitrate is colorless transparent rhombic tabular crystal.Relative density 4.35 (19 . Melting point 208.6 . Decompose when heats up to 445 . Easily dissolve in water and ammonia, soluble in ether and anhydrous alcohol. Slightly soluble in anhydrous alcohol, hardly dissolve in strong nitric acid. Solution assumes weak acidity. Pure silver nitrate is stable to face the light. It will become black when contacts with hydrogen sulfide and organic matter. Moist silver nitrate is easily to become dark under the light. As oxidant, it can make protein concrete, has corrosive action to body.Relative molecular mass:169.87.

 

 

Silver nitrate is a colorless crystalline solid. It dissolves in water. Most silver compounds do not dissolve in water. It can get dark if light shines on it. It is an oxidizing agent. Most of the times the silver ion is reduced, but sometimes the nitrate ion is reduced. It reacts with copper to make silver crystals and copper nitrate. It turns into silver, nitrogen dioxide, and oxygen when it is heated. It is the least expensive silver compound. It reacts with bases to make dark brown silver oxide.

 

 

 

Silver nitrate used for making negative of taking pictures, vacuum flask refill and mirror manufacture, but also uses in silver plating, printing, corrosive agent in medicine, hair dye, analytical agent, preparation of other silver salt and colorfast ink.
