CHEM 104 LAB 6
Notebook
Experiment #: 6
Title:
Electrochemistry
Purpose: To study how redox reactions occur, and to see how the metal reactivity
series can predict
whether a reaction will occur or not.
Procedure:
Experiment #1
Using a lightbulb device to test the conductivity of:
-Metal cylinder
-Water
-Sugar water
-KCl water
-Soda (coke)
Experiment #2
Test Tube of copper sulfate: stick iron nail into copper solution and let sit.
Experiment #3
Beaker and test tube of HCl and ribbon of magnesium. Put ribbon into test tube. Observe
- Steam, bubbling of H2 gas, etc.
Experiment #4
Take a sheet of copper metal into a solution of Fe2+ to see if a similar reaction to the
copper solution and iron nail will occur.
Experiment #5
-Construct a voltaic cell using copper (cathode) 1M solution and zinc (anode) 1M solution
-Attach copper wire and missy zinc to the alligator clips on the wire attached to the meter
-Place copper solution and zinc wire into zinc solution and record voltage
-Take a bridge filled with KCl auger and place into two beakers. Retests and record voltage
