Procedure:
N/A
Discussion:
Explain that each container holds one mole of the labeled chemicals
Hazards:
Lead and sodium dichromate are thought to be carcinogenic. Although the containers are sealed, handle the demonstration with proper PPE including gloves and goggles. If accidental release occurs refer to MSDS.
