14. In neutral aqueous solution,E°for the Mn3+/Mn2+ couple is +1.54 V. At pH 14,E°for the Mn(OH)3/Mn(OH)2 couple is t0.15 V. Which of the following statements is incorrect?
(A) At pH 14, Mn(II) and Mn(III) both precipitate from aqueous solution as hydroxides
(B) Mn(III) is less stable with respect to reduction to Mn(II) at pH 14 than at pH 7
(C) The Mn(OH)3/Mn(OH)2 couple refers to an equilibrium involving Mn(III) and Mn(II)
(D) At pH 7, Mn3+(aq) is a relatively strong oxidizing agent
