1. Calculate the value of ?G for the galvanic cell described in problem 1.
2. How many mL of .1000 M sodium hydroxide must be added to 500 mL of .1000 M formic acid to prepare a buffer solution with a pH of 4.00?
Write the cell diagram for a galvanic cell consisting of a silver electrode in contact with .300 M silver nitrate solution and a copper electrode in contact with a .500 M copper nitrate solution.© BrainMass Inc. brainmass.com March 4, 2021, 8:01 pm ad1c9bdddf
Please see the attached file.
The cell can be drawn as shown above
The cell reaction can be written as
EMF of the cell can be calculated as Ecell= EL - ER
Ecell = 0.3-0.8
EMF of the cell at 250C can be calculated using Nernst equation
Ecell = E0cell - 0.0591/nlog [oxidized]/[Reduced]
Ecell= -0.5-0.0591/2log [0.5]/[0.6]
The solution calculates the value of ?G for the galvanic cell described in problem 1.
