Iodine clock reaction sources of error
Web11 jun. 2024 · A clock can be formed from molecules that react at a rate from the time the chemicals are mixed to the time the reaction occurs. Explanation: There are two forms of iodine: Element form (Iodine): I2 + starch -------> blue Ion form (Iodide): I- + starch --------> colorless There are two reactions taking place simultaneously in the solution:

As the concentration of [H30+] kept on increasing from 0.0648 to 0. 0.26M so did the reaction rate from 2.66E-8to 6.79E-8in a linear relationship giving rate order of 1 which means concentration is directly proportional to rate of reaction.
WebThe equations below are examples from a Hydrogen Peroxide Iodine Clock Reaction: Reaction 3: 〖2I〗_ (3 (aq))+starch →starch I_5 complex +I_ ( (aq)) (Shakhashiri, B. 1992). The first equation/reaction (determining step) shows that the iodide particles react with hydrogen peroxide to form triiodide ions.
