KBr(s) → K+(aq) + Br-(aq)
This equation shows that potassium bromide (KBr) in solid state (s) dissolves in water (aq) to form potassium ions (K+) and bromide ions (Br-) in aqueous solution.
It's important to note that this is a reversible reaction. This means that the potassium and bromide ions can recombine to form solid potassium bromide again. However, in most cases, the solubility of potassium bromide in water is high enough that the majority of the salt will remain dissociated in solution.
