Electrochemistry: Galvanic Cells and the Nernst Equation
Name Nikhil Kishore TA’s Name James Barnes
Below is a lab activity that is based on a series of virtual lab exercises and videos that have been
put together by The ChemCollective, an online resource for learning chemistry. To begin,
please visit the below website:

The above link will lead you through a series of activities aimed at improving your
understanding of Galvanic Cells. First you will take a series of observations to determine if
process is spontaneous. Based upon those observations, you will create an activity series,
listing the metals in order of their reactivity. Second, you will construct a series of virtual
galvanic cells and use those to power a stopwatch. Third, you will determine the standard
reduction potential of an unknown metal; comparing its reduction potential to a standard list,
you will identify the unknown. Finally, you will create a situation in which the cells are not in
the standard condition and measure the cell potential; using the Nernst equation, you will
determine the concentration of an unknown solution.

Step 1: - Investigating redox reactions of some metals
and solutions of metal salts
Activity: Investigating redox reactions.
After watching the video “Zinc strip in copper nitrate solution”, and reading the
instructions, click on the link labeled “start” just below the drawing of the pencil tip.
Follow the direction to complete the 3x3 grid. Answer the below questions for the
portion of the activity in which Sn(s) is placed in AgNO3(aq)
1. Is there a reaction? (circle the correct response) Yes
2. How many electrons are transferred 2e-
3. Write the balanced redox reaction for the combination of AgNO3(aq) and Sn(s)
2AgNO3 (aq) + Sn (s) à Sn(NO3)2 (aq) + 2Ag (s)
Once the 3x3 square is complete, click on the link in the bottom right of the page to
