Factors affecting Galvanic Cells

Extracts from this document...

Introduction

Factors affecting Galvanic Cells Problem: If and how changes in the solutions as well as their concentrations affect the voltage in a galvanic cell? Variables: - Independent: * Type of solution used: Cu(NO3)2, Zn(NO3)2, Pb(NO3)2 * The concentration of the each solution. ...read more.

Middle

Circuit wire - Beakers - Salt Bridge - Sand Paper - Crocodile clips - Graduating Cylinder - Cu(NO3)2, Zn(NO3)2, Pb(NO3)2 - Weight Scale Procedure: - Set up a beaker with 300 mL of 1M Cu(NO3)2 - Set up the voltmeter so it's connected to the power supply, correctly and with crocodile clips - ...read more.

Conclusion

Wet each strip with Cu(NO3)2 and insert into the solution. Repeat for each of the three remaining salt solutions. - Start the power supply for 5 minutes and record the amount of voltage created. Do so three times and record the information - Repeat above steps for 0.5M, 1.5 M and 2M and then repeat so with the remaining solutions. ...read more.
