Silver Nitrate
Chemical Name: Silver Nitrate
Synonyms: Silver(I) nitrate; Silver Ion standard solution Fluka
CAS No.: 7761-88-8
Relative molecular mass: 169.87
Molecular Formula: AgNO3
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 night. As oxidant, it can make protein concrete, has corrosive action to body.
