Reaction between potassium iodide and bromine
WebIf bromine is added to a solution of sodium iodide, a reaction occurs: bromine + sodium iodide → iodine + sodium bromide. ... potassium bromide and potassium iodide. 5 of 6. WebThe reaction between bromine and potassium iodide can be explained in the same way. 2KI(aq) + Br 2 (aq) 2KBr(aq) + I 2 (aq or s) Bromine is better at forming negative ions than iodine is. So bromine takes electrons from the iodide ions and leaves iodine molecules. This is yet another redox reaction.
