Chemical properties: Silver bromide can be used in synthesis to form amine complexes owing its capacity to react easily with ammonia. Some of the complexes can be produced are:AgBr + nNH3→ [Ag(NH3)2]+AgBr + nNH3→ [Ag(NH3)2]
, obtained by dissolving silver oxide in aqua ammonia. When dry it explodes violently on the slightest percussion. (b) Silver fulminate, a white crystalline substance, Ag2C2N2O2, obtained by adding alcohol to a solution of silver nitrate; – also called fulminate of silver. When dry ...
Silver chloride, silver bromide, silver oxide are soluble in ammonia solution. Silver chloride is soluble in solutions which contains ligands such as chloride, cyanide, triphenylphosphine, thiosulfate, thiocyanate and ammonia. But, not soluble in nitric acid....
Dye 1 sensitizes a silver bromide-ammonia-emulsion the maximum being at 549 nm. Dye 2 sensitizes a silver bromide-ammonia-emulsion the maximum being at 545 nm. Dye 3 sensitizes a silver bromide emulsion which contains 3 mole-percent of silver iodide the maximum being at 646 nm and the sensi...
The present invention relates to a light-sensitive emulsion, and a light-sensitive photographic material containing the same, comprising silver bromoiodide grains of a core shell structure comprising: a) an inner core consisting essentially of silver bromide or silver bromoiodide and having a silver ...
