Required Training	Required PPE
UC Lab Safety Fundamentals	Lab coat, safety glasses/goggles, nitrile gloves

Equipment	Chemicals
	207.21 g Lead metal
	298.0 g Sodium dichromate, dihydrate (Na₂Cr₂O₇*2H₂O)
	342.3 g Sucrose (C₁₁H₂₂O₁₁)
	251.5 g Cupric sulfate, pentahydrate (CuSO₄*5H₂O)
	58.5 g Sodium chloride (NaCl)
	18 g Water (H₂O)

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.

SOP
