The reaction between potassium iodide (KI) and bromine (Br₂) produces potassium bromide (KBr) and iodine (I₂) gas. Here's the balanced chemical equation:

2KI (aq) + Br₂ (l) → 2KBr (aq) + I₂ (g)

Here's what each part of the equation represents:

* KI (aq): Potassium iodide in an aqueous solution (dissolved in water)

* Br₂ (l): Liquid bromine

* KBr (aq): Potassium bromide in an aqueous solution

* I₂ (g): Iodine gas

Explanation of the Reaction:

This reaction is a classic example of a single displacement reaction. Bromine (Br₂) is more reactive than iodine (I₂), so it displaces iodine from the potassium iodide compound. The bromine atoms bond with potassium to form potassium bromide, while the iodine atoms combine to form iodine gas.
