A traditional method for the manufacture of KBr is the reaction of potassium carbonate with an iron(III, II) bromide, Fe 3 Br 8, made by treating scrap iron under water with excess bromine: [4] 4 K 2 CO 3 + Fe 3 Br 8 8 KBr + Fe 3 O 4 + 4 CO 2 {\displaystyle {\ce {4 K2CO3 + Fe3Br8 -> 8 KBr + Fe3O4 + 4 CO2}}}

AgNO 3 (aq) + KBr(aq) → AgBr(s)+ KNO 3 (aq) Although less convenient, the salt can also be prepared directly from its elements. Modern preparation of a simple, light-sensitive surface involves forming an emulsion of silver halide crystals in a gelatine, which is then coated onto a film or other support.
