Silver Bromide Precipitation

AgNO3 + NaBr → AgBr↓ + NaNO3

Descripción general

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.
