Did you know?
WebIodine clock reactions. There are several reactions which go under the name "iodine clock". They are all reactions which give iodine as one of the products. This is the simplest of them, but only because it involves the most familiar reagents. The reaction we are looking at is the oxidation of iodide ions by hydrogen peroxide under acidic ... WebThere were two consecutive reactions happening in the reaction vessel. The first reaction was a redox reaction where iodide ions and persulfate reacted to oxidize the iodide ions to iodine and reduce the persulfate to sulfate ions. The chemical equation for this reaction is: 2I-+ S 2 O 8 2-→ I 2 + 2SO 4 2-By applying the steady-state approximation, the overall rate …
WebThis iodine clock reaction project can apply to the real world in different ways, but I think the biggest way is concentration. After doing some research, I found out that it can teach you about concentration, because it shows you that once you add any bigger amount to a substance, it changes reaction time, or in a real world case, how a substance feels, acts, … WebStir thoroughly.
