• Uses: Silver Bromide is used in the spectroscopic study of silver halides in montmorillonite and their antibacterial activity, also used in the antimicrobial compositions for use in wound care products. A yellowish powder made by the combination of any soluble bromide with silver nitrate. Silver bromide could also be formed by exposing metallic silver to the fumes of bromine as in the daguerreotype process. It is soluble in sodium thiosulfate, potassium bromide, and potassium cyanide solutions. Silver bromides were secondary halides for the paper negative processes, albumen negative process, and wet or preserved collodion processes. Silver bromides were the primary halides for the silver bromide collodion emulsion negative and the silver bromide gelatin emulsion processes. Silver bromide is the most photosensitive silver halide.
