Potassium Bromide (KBr) is a common ionic salt, which is used in a variety of applications. It is a strong electrolyte and is highly water-soluble. However, it is very toxic in large amounts. For this reason, it is only recommended that you use it in a hygienic environment.
Potassium bromide has a melting point of about 730 degrees Celsius. In aqueous solution, the ion has a pH of about 7. The compound also has a low refractive index. This makes it a good choice for infrared spectroscopy.
One of the most widely-used chemical compounds, potassium bromide is found in a wide variety of applications. These include optics, photography, synthesis, and color photo bleach. Aside from being used in a wide range of industries, it is also considered an antiepileptic medicine for veterinary uses.
KBr is widely used as a prism material for infrared spectroscopy. The compound is also used in optical applications in the MWIR and LWIR wavebands.
KBr has been used in the production of silver bromide films, as well as in alkaline developers for gelatin plates. However, it is no longer used as a primary halide in photographic processes.
KBr solutions are commonly used as nucleophiles in organic chemistry. KBr solutions are also found to be useful shape-control agents.
It is important to keep potassium bromide in a dry environment. Using it in a humid environment can increase its toxicity. If you are planning to use it, be sure to maintain a temperature of about 30 degrees Celsius.
