Cautions

Discovery lab.!  Examine the effect of moving the electrode around in the cell, does it effect the voltage measured?

• Inquire as you go, ask questions of self, each other, me. Think in the notebook, and solve problems as you go.

Wear safety glasses!

Note carefully the safety precautions on page 156 of the lab text.
 
Corrections to text:
