Silver Chloride Photodecomposition

2AgCl → 2Ag + Cl₂

अवलोकन

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.

रोजमर्रा का उदाहरण

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

औद्योगिक महत्व

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