Potassium iodate clock reaction
WebIn this iodine clock reaction, the reaction being monitored is: I₃⁻ + starch blue-black complex However, in order to form the triiodide ion, the following reaction has to occur: 3 I⁻ + 2 H⁺ + H₂O₂ I₃⁻ + 2 H₂O (The iodine was from a potassium iodide solution). To convert the triiodide ion back to the iodide ion which does not form a complex http://www.annualreport.psg.fr/FX05slh_iodine-clock-reaction-catalyst-potassium-iodide.pdf

WebThe ‘Landolt iodine clock reaction’ is a well known experiment characterised by a notable clear-to-blue colour change, this experiment is often used to determine the rate at which reactions take place. This colour change takes place when I2 reacts with 1% starch to form a blue starch and iodine solution. WebIn this reaction, potassium iodate and sodium metabisulfite react to form iodine. The starch solution serves as an indicator of the end of the reaction by forming a deep-blue colored starch–iodine complex. The reaction time can thus be measured by not-ing the time until the appearance of the blue color for each trial.
