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.
