- Description:Gold nanoparticle demonstration
- Cat. no.:470336-160
- Includes:Instructional manual and SDS booklet
- No. of Uses:5
Perform a reduction reaction to understand and demonstrate the properties of gold nanoparticles.
- Understand and demonstrate properties of nanomaterials
- Aligned to NGSS practices
Explore the interesting properties of nanomaterials by reducing a solution of gold (III) chloride to form colloidal gold nanoparticles. As the reaction occurs, the mixture undergoes multiple color changes before becoming the bright red color characteristic of small gold nanoparticles. There are enough materials to complete the demonstration five times.
