    Chemical properties

    1.Replacement reaction
    AgNO3+HCl=AgCl↓+HNO3
    Cl2+H2O=HCl+HClO HCl+AgNO3=AgCl↓+HNO3
    MnCl2 +2AgNO3=Mn(NO3)2+2AgCl↓
    2AgNO3+2NH3+H2O=Ag2O↓+2NH4NO3
    2NaOH+2AgNO3=2NaNO3+Ag2O↓+H2O
    NaCl+AgNO3=AgCl↓+NaNO3
    AgNO3+NH3·H2O=Ag2O↓+H2O+NH4NO3
    AgNO3+3NH3·H2O=Ag(NH3)2OH+NH4NO3+2H2O
    HBr+AgNO3=AgBr↓+HNO3
    2. Decomposition reaction
    2AgNO3=△=2Ag+2NO2↑+O2↑
    3. Redox reaction
    (1) Replacement reaction
    N2H4+4AgNO3─→4Ag+N2+4HNO3
    　　H3PO3+2AgNO3+H2O─→2Ag+H3PO4+2HNO3
    2AgNO3+Cu=Cu(NO3)2+2Ag
    (2) Decomposition reaction
    2AgNO3=△=2Ag+2NO2↑+O2↑
    (3) Other redox reactions
    4AgNO3+2H2O=4HNO3+4Ag↓+O2↑(primary battery reaction)

    For precipitating chloride ions in analytical chemistry. In producing other silver salts in inorganic industry. In producing conductive adhesive, new model gas cleaning agent, and A8x molecular sieve in electronic industry, and etc.  

    Storage

    Keep in cool and well-ventilated warehouse with temperature less than 30℃ and relative humidity less than 80%; Keep in brown bottles in laboratory. Keep away from fire and heat sources. The package must be sealed to protect from damp. Separate from flammable matters, reducing agents, alkalis, alcohols and edible chemicals.
