The oxidation state of Mn in KMnO₄ is: A)+1 B)-1 C)+5 D)+7 E)none of the above

Question

Quizplus · Accepted Answer

In KMnO₄, the total charge of K, O, and S is: K: +1 O: -2 (x1) S: -2 (x3) = -6 The total charge of the compound is 0. Therefore, the total charge of Mn is: +1 - 6 + x = 0 x = +5 Therefore, the oxidation state of Mn in KMnO₄ is +5. Choice C (+5) is correct, and choices A (+1) and B (-1) are incorrect. Choice D (+7) is not a possible oxidation state for Mn.
