Lab Procedure: Iodine Clock Reaction ChemTalk
WebThe iodine clock reactionis a classical chemical clockdemonstration experiment to display chemical kineticsin action; it was discovered by Hans Heinrich Landoltin 1886.[1] The iodine clock reaction exists in several variations, which each involve iodinespecies (iodideion, free iodine, or iodateion) and redoxreagents in the presence of starch. WebCLOCK REACTION . In this experiment, the effect of temperature and concentration on the rate of a chemical reaction will be studied. The reaction chosen, frequently termed the “clock reaction”, is actually a series of consecutive reactions represented by the following equations: BrO 3 1-1+ 6 I - + 6H+ Br1-+ 3I 2 + 3 H 2O (1) -I 2 + 2 S 2O 3 the pettiness prayer
