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.

Rating:

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
• 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
