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.

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?
