Question
1. You have the following supplies needed to build an electrochemical cell. 1.0 M Co2+ solution, a strip of solid Co, 1.0 M Ag+ solution, a strip of solid Ag, salt bridge
a. Write the spontaneous redox reaction and calculate the standard cell potential.
b. Draw a diagram of how you will set up the cell according to instructions in your lab manual.
c. Calculate the cell potential if the concentration of Ag + was 0.010 M and the concentration of Co2+ was 0.50 M.
2. Describe how an electrochemical cell can be used to determine the potential of a half cell reaction.
Explanation / Answer
2. I believe voltage is the electrical power of the moving electrons, but determined by the metal's individual oxidation or reduction potential. The electrons are just part of the chemical equation showing where the electrons go and are only needed to balance the half reactions of the redox equations because the mass must be conserved.
If 2H+(aq) = H2 (g) then there would be missing particles that just dissappeared.
I hope this muddled interpretation helps.
Write decomposition reaction for 1 and redox reaction and draw ,its easy first part.
