This experiment tests the effect of different sulfuric acid concentrations on the rate of the iodine clock reaction. The initial concentrations and volumes of all other reactants are the same in all four vials. The greater the acid concentration, the faster the reaction.

AP Chem Lab: Peroxide/iodine clock reactions ... Overview: In this lab, you will attempt to measure the rate of a reaction under various conditions. Your goal will be to experimentally determine the order of the reaction with respect to the reactants as well as the rate constant for the reaction at room temperature.

THE IODINE CLOCK REACTION ... In the iodine clock reaction, there are really two processes happening simultaneously. The first is a slow reaction producing iodine: ... The reaction produces iodine which can stain skin and fabric. It can be destroyed by reaction with sodium thiosulfate solution. Drink neither Solution A or B.
