Decomposition of Silver Chloride (Photodecomposition)

2AgCl → 2Ag + Cl2

Übersicht

Silver chloride decomposes when exposed to light, forming metallic silver and chlorine gas. This photosensitivity is the foundation of silver-based photography. The white compound darkens to gray or black as metallic silver particles form on the crystal surface.

Alltägliches Beispiel

Traditional film photography relies on the photodecomposition of silver halides (including silver chloride) to capture images.

Industrielle Bedeutung

While digital photography has largely replaced film, silver halide photosensitivity is still used in specialty photographic papers, holography, and some medical imaging applications.
