It serves as a precursor for silver mirrorsplating photographic film emulsions antiseptic cauterant for woundsgranulation tissue analytical reagent for halide detection (AgClAgBr precipitates) and in explosivesinks.

Its primary purpose is providing Ag ions for selective precipitation of halidescyanides and bactericidal action via protein denaturation with light sensitivity causing black Ag metal formation.

Silver nitrate (AgNO3) is a white crystalline solid ionic compound consisting of Ag cations and trigonal planar NO3 anions with molecular weight 169.87 gmol density 5.35 gcm3 melting point 212C decomposition at 440C to silver NO2 and O2 and highly water-soluble (219 gL at 20C) forming acidic solutions.
