Kinetics- Kinetics of Oxidation of Iodide Ion by Peroxide

Kinetics of Oxidation of Iodide Ion by Peroxide

Description: The concentrations of acid, Iodide, and peroxide are varied in several trials, and the time to reach a predetermined color (due to Iodine production) is measured. The reaction is first order for each species.

Hazard: Some

  • Acute toxicity hazard
  • Inhalation  hazard
  • Skin corrosion hazard
  • Oxidizing solid
  • Oxidizer
  • Corrosive to metals
  • Specific organ toxicity – thyroid
  • Electric shock hazard

Effectiveness: Good

  • Results are clearly  observable without guidance
  • Good connection from demo to course material
  • Moderate effects are seen by audience
  • Time to results is medium

Difficulty: High

  • Some concerted or timed manipulations
  • Multi-step procedures with varying results
  • Volume-dependent addition for proper results
  • Experiments in which data recording or display is necessary
  • Demos require training or extended practice to perform correctly

Safety Precautions:

  • Eye protection required
  • Gloves required
  • Use of UL approved three-prong plug and outlet
  • Perform in a well-ventilated area
  • Avoid inhalation of vapors
  • Absorbent materials on hand
