The oxidation variety of potassium in potassium bromide is 1.

You are watching: Potassium combined with bromine is...

Synthesis

One way to do potassium bromide is to react the hydroxide through hydrobromic acid. The result salt deserve to then it is in purified by recrystallization.

KOH(aq) + HBr(aq) → KBr(aq) + H2O(l)

While no a normal route of preparation due to the fact that of the expense, potassium steel reacts vigorously with all the halogens to form potassium halides. So, it burns through bromine, Br2, to type potassium(I) bromide, KBr.

2K(s) + Br2(g) → 2KBr(s)
