Does PH Have an Effect on the Cell Potential (E_cell)

question 68

Multiple Choice

Does pH have an effect on the cell potential (E_cell) for the following oxidation-reduction reaction?

• A)Yes, because E_cell values for all redox reactions depend on the pH.
• B)Yes, because E_cell values for redox reactions involving the hydronium ion depend on the pH.
• C)No, because E_cell values for redox reactions depend only on the major species in the reaction, in this case, Fe^{2 } , MnO₄ ^ , Fe^{3 } , and Mn^{2 } .
• D)No, because E_cell values for redox reactions depend on concentrations and temperatures but not on pH.
• E)No, because E_cell values for redox reactions do not depend on the pH.
