Reaction between potassium iodide and bromine
WebReplacing -OH by bromine. Rather than using hydrobromic acid, you usually treat the alcohol with a mixture of sodium or potassium bromide and concentrated sulphuric acid. This produces hydrogen bromide which reacts with the alcohol. The mixture is warmed to distil off the bromoalkane. Note: You will find practical details of this reaction on ... WebThe reaction mixture turns darker as iodine solution forms. The slideshow shows what happens when solutions of chlorine, bromine and iodine are added to various potassium halide salts. Adding ...
Reaction between potassium iodide and bromine
Did you know?
WebThe potassium bromide solution gradually turns pale yellow due to the formation of bromine. The potassium iodide solution turns yellow-brown due to the liberation of iodine by the chlorine. When the reactions have finished, add three drops of sodium hydroxide solution to the reaction vessel to stop the generation of chlorine and replace the lid. WebThe iodide ions will be in a solution of a salt like sodium or potassium iodide. The sodium or potassium ions will be spectator ions, and are completely irrelevant to the reaction. In the chlorine and iodide ion case, the reaction would be: Cl 2 + 2I- 2Cl- + I 2. The iodide ions have lost electrons to form iodine molecules. They have been oxidised.

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.
