Potassium Iodide Experiment at Edward Acosta blog

Potassium Iodide Experiment. Acts as the catalyst to decompose the hydrogen peroxide into water and oxygen gas rapidly. More specifically, it is the iodide ion that catalyzes the reaction. Mix a solution of hydrogen peroxide with potassium iodide, starch and sodium thiosulfate to see a colourless solution suddenly turn dark blue. Method 1) quickly pour ~10 ml of the saturated potassium iodide solution into the cylinder and step back, as a large volume of. This demonstration can be used at secondary level as an introduction to some of the ideas about kinetics. The rapid evolution of oxygen gas is produced by the following reaction: In the demonstration described below potassium iodide is used to catalyze the hydrogen peroxide. Introduce your students to rates of reaction and kinetics with the iodine ‘clock’ reaction. Helps trap the oxygen gas, creating foam. The proposed mechanism is as follows: 2 h 2 o 2 (aq) = 2 h 2 o (l) + o 2 (g) + heat; The chemical reaction in this demonstration is between the hydrogen peroxide and a solution of potassium iodide and dishwashing detergent that captures the gases to make bubbles.
