Dear Student,

if the H+ concentration is decreased from 1M to 10-4 M at 25 degree celsius for the couple MnO4 -/Mn+2, then the oxidising power of the MnO4 -/Mn+2 couple decreases by a) -0.18V b)0.38V

if the H⁺ concentration is decreased from 1M to 10^-4 M at 25 degree celsius for the couple MnO₄ ^-/Mn⁺², then the oxidising power of the MnO₄ ^-/Mn+2 couple decreases by a) -0.18V b)0.38V
