1.	For which of these oxidation/reduction pairs will the reduction potential vary with pH? I `AmO_(2)^(2+)//AmO_(2)^(+)` II. `AmO_(2)^(2+)//Am^(4+)` III `Am^(4+) // Am^(2+)`A. I onlyB. II onlyC. I and II onlyD. I, II only III
Answer» Correct Answer - B `4H^(+) + AmO_(2)^(2+) + 2e^(-) rarr Am^(4+) + 2H_(2)O` It includes `H^(+)` ions, hence the electrode potential depends on pH
