Silver Nitrate 99.8% AR Grade Reagent
Cas Number:7761-88-8
Formula: AgNO3
Molar Mass:169.87
EC Number:231-853-9
Physicochemical properties:
Colorless transparent large crystal or white small crystal. Odorless. The pure product does not change black in light and air, but it can promote photoreduction and blackening in the presence of hydrogen sulfide or trace organic matter. It is a pale yellow liquid after melting and remains white after curing. When heated to 440 ° C, it decomposes into silver, nitrogen, oxygen and nitrogen oxides. It has a coagulation effect on proteins.
Usage:
Determination of chlorides, bromides, iodides, cyanides and thiocyanates. A catalyst for the determination of manganese. plating. Produce silver salt. photography. Porcelain coloring.
Packing:
500g/25kg
