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 anhcohol, 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
