Quick Summary

Potassium bromide (KBr) is a crystalline salt with a saline taste. It has been used historically as a sedative and in photography. It is a compound of potassium and bromine, a chemical element discovered in 1826. Bromine is a deep red, noxious liquid and a member of the halogen group.12

Potassium bromate (KBrO₃) is a different crystalline salt used as an oxidizing agent and to improve flour for baking.3

… (ZnSe), cesium iodide (CsI), or potassium bromide (KBr), coated with silicon or germanium are employed. Below 200 cm⁻¹ Mylar films of varying thickness are used to cover narrow portions of the region. Thermal detection of infrared radiation is based on the conversion of a temperature change, resulting from such radiation…

Physiological basis of taste
…of inorganic salts (such as potassium bromide) are complex; epsom salt (magnesium sulfate) is commonly sensed as bitter, while table salt (sodium chloride) is typical of sodium salts, which usually yield the familiar saline taste. Sweet and bitter tastes are elicited by many different classes of chemical compound.
