Silver Bromide

Silver Bromide

                       
                             
  • Silver bromide (AgBr), a soft, pale-yellow, water insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials.
  • The salt can be found naturally as the mineral bromargyrite (bromyrite).
  • Although the compound can be found in mineral form, AgBr is typically prepared by the reaction of silver nitrate with an alkali bromide, typically potassium bromide.
