Silver Chloride Photodecomposition

2AgCl → 2Ag + Cl2

Genel Bakış

Silver chloride darkens upon exposure to light as photons provide enough energy to reduce Ag⁺ to metallic silver. This photosensitivity of silver halides is the fundamental chemistry behind traditional photography. The released chlorine atoms combine to form Cl₂ gas.

Günlük Örnek

Traditional black-and-white photography relied on this reaction — light hitting AgCl-coated film created a latent image of metallic silver.

Endüstriyel Önemi

Silver halide photography dominated imaging for 150 years. AgCl is still used in photochromic lenses that darken in sunlight.
