Level of Difficulty
Moderate. This experiment requires the purchase of two chemicals and the supervision of an adult.
Materials Needed
- silver nitrate (a salt-indicator solution, which can be purchased from science supply catalogs)
- Biuret solution (a protein-indicator solution, also available from science supply catalogs)
- glass test tubes or glass cups
- test tube rack
- food from one meal
