WebMentioning: 6 - Research on the glyoxal clock reaction has led to adaptation of the clock reaction to a general chemistry experiment. This particular reaction is just one of many that used formaldehyde in the past. The kinetics of the glyoxal clock makes the reaction suitable as a general chemistry lab using a Calculator Based Laboratory (CBL) or a LabPro. The …
WebIn this iodine clock reaction, the reaction being monitored is: 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. WebJul 20, 2024 · Two reactions actually occur in the iodine clock: H 2 O 2 + 3I − → I 3 − + 2H 2 O and I 3 − + 2S 2 O 3 2 − → 3I − + S 4 O 6 2 − The solution changes color as soon as all of the thiosulfate has been consumed. In the following video, we see how the concentration of the iodide ion affects the rate of reaction.
