Write an equation for the reaction that takes place when bromine is added to an aqueous solution of potassium iodide. - Leaving Cert Chemistry - Question d - 2001

When bromine ( ext{Br}_2) is added to an aqueous solution of potassium iodide (KI), the following reaction occurs:

$\text{Br}_2 + 2\text{KI} \rightarrow 2\text{KBr} + \text{I}_2$

In this reaction, bromine displaces iodine from potassium iodide, resulting in the formation of potassium bromide and iodine.
