WebIodine clock reactions come in a number of variations, but they generally all use starch to show a sudden purple-black colour at the end of the reaction; A common iodine clock … Webdeciding factor in the rate of production, it is possible that there are many other factors that would have a more powerful, and less intuitive, effect. In order to study the effect of a molarity of solution on the time of reaction, the reactants of the “Clock reaction”, or the reaction between and , will be modified.
