Sulfuric acid is mixed with potassium iodide solution to produce a mixture of H+ and I- ions. Excess hydrogen peroxide is added to the mixture so that iodine is produced by the reaction below: 2. Starch solution added.
Web24 jan. 2024 · Students are fascinated by sudden changes in a reaction. For this reason, variations on the iodine clock reaction can engage students. You can show this as a demonstration (rsc.li/2B4Y67N) or challenge your students to produce a mixture that will suddenly change colour after a defined time (rsc.li/2my8ShE). WebA rate- concentration graph for the iodine clock reaction. From this graph we can see that the rate of reaction is directly proportional to the concentration of potassium iodide: As …
WebThe initial rate is the instantaneous rate at the start of a reaction when the time, t is zero (t = 0). The initial rate can be found by measuring the gradient of a tangent drawn at t = 0 … WebThe rate of reaction is first-order in potassium iodine.
