- Part 2: Nickel electroplating lab is a perfect illustration of Chemical Kinetics and Equilibrium concepts. We will prepare our own nickel salt from pure nickel metal, build our own electrochemical plating cell, and plate various objects with bright-nickel. This will take two lab sessions. Handouts will be provided when we get here.

Video shows a good example of "chemical equilibrium"
What is meant by "chemical equilibrium"?
- Thermodynamics answers the question, "Will a reaction occur?"
- Kinetics answers the question, "How fast will a reaction go?"
- Chemical equilibrium answers the question, "How far will a reaction proceed before it stops?" If you can't get a reaction to go very far, it may not be very useful in a practical sense.
