Silver Bromide Precipitation

AgNO₃ + NaBr → AgBr↓ + NaNO₃

ภาพรวม

Silver bromide precipitates as a pale yellow solid with Ksp = 5.4 × 10⁻¹³. It is much less soluble than AgCl. Silver bromide is photosensitive, decomposing in light to form metallic silver and bromine. This photosensitivity made AgBr the key compound in photographic film emulsions.

ตัวอย่างในชีวิตประจำวัน

All analog photographs ever taken relied on silver bromide crystals darkening when exposed to light in the camera.

ความสำคัญทางอุตสาหกรรม

Silver bromide was the foundation of the photography industry for over 150 years. While digital has replaced film, AgBr is still used in specialty medical and scientific imaging.
