Activities of Metals
Some metals are more
reactive than others
We will develop an activity series
by comparing how different
metals react with the same ions
in aqueous solutions.
Activities of Metals
Safety precautions:
•Goggles
•Gloves
•Aprons
•Nitrates are poisonous:
Do not eat them
Wash your hands.

Procedure
1. Use sandpaper or a file to clean
your samples of metals
2. Observe what happens in each
cell
3. After five minutes, record your
observations your data table
4. Answer “Analyze and Conclude”
questions on page 301.
Clean-Up
Clean-Up
1. I will provide containers for solid
and liquid waste
2. DO NOT rinse the reaction plate
under running water. IT WILL
SPLASH IN YOUR FACE!
3. Place the reaction plate into water
bath to be cleaned.
Do today:
1. Write the procedure
2. Set up your data table
3. Answer the following pre-lab
questions:
Pre-Lab Questions:
1. How can you tell if a reaction is
happening?
2. Why do you need to clean the
metals with sandpaper?
3. What are you cleaning off?
4. If metal X reacts with YNO3, which
is higher on your activity series:
X or Y?
