Description and Uses

The basis of nearly all photographic silver halides with the exception of the daguerreotype process, silver nitrate is a heavy white crystal made by dissolving elemental silver in nitric acid followed by evaporation. It is soluble in water, ether, and glycerin. Silver nitrate is not sensitive to light, but when combined with an organic material, a halogen, or a halide it will reduce back to a metallic state when exposed to light.
