용도

Silver nitrate is employed in Silver plating, photography, manufacturing of other silver compounds, mirrors, coloring porcelain, and staining in histology. It finds use as a stain in scanning electron microscopy, and a key ingredient in several silver-based antiseptic and antibacterial pharmaceutical compositions. Silver(I) nitrate can be used to separate mixtures of alkenes by selective absorption, and for deprotection and oxidation reactions in organic synthesis. It is widely used as an analytical reagent owing to its immediate reaction with halide ions forming insoluble precipitate of silver(I) halides.

참고

Sensitive to light; hence store in light resistant containers. Corrosive solid. Relatively more stable to light than other salts. Color changes to grey or greyish black on exposure to light or air in the presence of organic matter.
