Iodine clock reaction rate
Webdiscussion.htm. Iodine Clock Reaction. "Iodine Clock" refers to a group of reactions which involve the mixing of two colorless solutions to produce a solution which remains … WebClock reactions have been a method of studying chemical kinetics over the years and are an example of an initial rates method (Braid and Train, 2015). The rate can be measured by the time taken for an observable endpoint to occur and in the iodine clock reaction, this is a colour change of blue/black.
