Decomposition of Silver Chloride (Photodecomposition)

2AgCl → 2Ag + Cl2

ภาพรวม

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.
