WebChemical kinetics of the iodine clock reaction Background The iodine clock reaction is an ideal candidate for studying kinetics as it uses relatively safe reactants and provides a visual indication of when it has reached its endpoint. It does this by turning a blue/brown color when the reaction has stopped. While the reaction is occurring it will remain clear …
Web26 nov. 2024 · Many students are unsure how to relate the IB chemistry topics to a real-world situation or problem that they can investigate. To help with this, I’ve produced a list of chemistry IA ideas, together with some example Research Questions (RQ). I’ve grouped them together according to the main experimental technique or measurement method. Webautomobiles. Catalysts operate by decreasing the value of the activation energy for the reaction. The decrease in activation energy resulting from the addition of a catalyst is shown in the figure above. An effective catalyst exists for the reaction of iodide with hydrogen peroxide. The catalyst is iron (II) ions dissolved in the reaction mixture.
WebWhen this reaction is run by itself, a yellow/brown color will slowly appear as iodine is produced. You will do this by using a second reaction, referred to as a “clock” reaction. The clock reaction indicates when a specific amount of I 2 has been produced by the primary reaction. The "clock" reaction you will use involves the reaction of a ...
