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. WebIodine Clock 6 o Thiosulfate molarity drops from [S2O3 2-]i to zero. o The I2 moles per liter consumed is [S2O3 2-]i /2 (see the balancing coefficients in Reaction 2). o The I2 consumed in Reaction 2 is produced in Reaction 1. o For each I2 mole produced, a mole of H2O2 is consumed (see balancing coefficients in Reaction 1). o Thus the H2O2 loss, …
