definition
Potassium bromide, chemically represented as KBr, is a potassium salt that was used over-the-counter in the United States until 1975 and was employed as an anticonvulsant and sedative in the early 20th century.
Its activity is due to the bromide ion (sodium bromide is equally effective).
application area
Potassium bromide is frequently used as infrared optical windows and components for general spectroscopy due to its wide spectral range. In infrared spectroscopy, samples are analyzed by grinding them with powdered potassium bromide and pressing them into a disk.
In addition to the synthesis of silver bromide, potassium bromide is used as a restrainer in black and white developer formulas.
It enhances the distinction between exposed and unexposed crystals of silver halide, thereby reducing fog.
