Potassium bromide is an ionic compound, which is a type of salt. It is a stable, white solid that dissolves easily in water. It is not a metal and its properties are very different from the elements it is made of.
Unlike potassium metal, potassium bromide does not react with air or water. The solid form is odorless, and when it is dissolved in water, it can have a pungent, bitter, and salty taste.
found: The compound was prepared by chemists like Antoine Balard in 1826, after he discovered the element bromine.
Made: It is formed in an exothermic reaction when solid potassium metal reacts with liquid bromine. 2K(s)+Br_2(l)rightarrow2KBr(s)+heat
Uses: It is used as a medicine for veterinary medicine to treat seizures in dogs. It was also used in human medicine in the past.
It contains the elements potassium (K) and bromine (Br).
Potassium is in Group 1, an alkali metal.
Bromine is in Group 17, a halogen.
