Hazard: High
- Acute toxicity hazard – oral, dermal, inhalation
- Corrosive to metals
- Skin corrosion hazard
- Aquatic toxicity hazard
- Serious eye damage
- Oxidizer
- Specific organ toxicity – thyroid, respiratory system

- Inhalation hazard
Effectiveness: Good
- Results are clearly observable without guidance
- Good connection from demo to course material
- Clear contrast between systems behavior
- Time to results is medium
- Good reliability
- Primary effects are observed
- Mild effects observed by audience
Difficulty: High
- Multi-step procedures with varying results depending on the order or amount of reagent addition
- Reactions containing toxic compounds
- Demos that require training or practice
- Simple manipulations for most to perform
Safety Precautions:
- Eye protection required
- Gloves required
- Perform in a well-ventilated area
- Use of UL approved three-prong plug and outlet
- Absorbent materials on hand
- Sodium bicarbonate on hand
- Avoid exposure to dusts, mists, and droplets
- Prevent release of reagents to the environment
