The purpose of this lab was to observe chemical changes, to write balanced equations, and to identify different types of reactions.
Types of Reactions Lab
Purpose: To observe chemical change, to write balance equations for the chemical reactions observed, and to identify different types of chemical reactions.
Procedure:
Prepare a suitable Data Collection Table to record all your observations.
- Reaction 1: Reaction of aluminum metal with copper (II) nitrate solution
Materials: small beaker, copper (II) nitrate solution and a piece of aluminum strip
1. Place an adequate amount of copper (II) nitrate solution into the beaker
2. Add a piece of Aluminum.
3. Record initial observations in the Data Collection Table.
3. Allow the solution to react with the aluminum for a few minutes.
4. Feel the test-tube.
5. Record final observations at the end of the experiment, after filtering the products when all the other procedures have been completed.
6. Clean Up: A metal pan is to be used to collect all solid materials.
- Reaction 2: Reaction between cobalt (II) chloride solution and sodium hydroxide solution.
Materials: small beaker, cobalt (II) chloride solution and sodium hydroxide solution
1. Place 10 ml of cobalt (II) chloride solution into a small beaker.
