What is the oxidation number assigned to manganese in KMnO4? (1) +7 (3) +3 (2) +2 (4) +4<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct oxidation number of manganese (Mn) in KMnO4 is +7<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the oxidation number of manganese in potassium permanganate (KMnO4), we follow these steps:<\/p>\n\n\n\n

    \n
  1. Identify the oxidation states of other elements:<\/strong>\n
      \n
    • Potassium (K) is an alkali metal in Group 1, so its oxidation state is +1<\/strong>.<\/li>\n\n\n\n
    • Oxygen (O) is typically assigned an oxidation state of -2<\/strong> in most compounds, except in peroxides or superoxides. Since we are dealing with KMnO4, where oxygen is part of the permanganate ion (MnO4^\u2212), each oxygen atom has an oxidation state of -2<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Set up the equation for the total charge:<\/strong>
      The total charge of the permanganate ion (MnO4^\u2212) is -1<\/strong>. In the formula KMnO4, the overall charge of the compound must be neutral, so the oxidation states must balance to zero. The equation for the oxidation states in KMnO4 is: (Oxidation\u00a0state\u00a0of\u00a0K)+(Oxidation\u00a0state\u00a0of\u00a0Mn)+4\u00d7(Oxidation\u00a0state\u00a0of\u00a0O)=0(\\text{Oxidation state of K}) + (\\text{Oxidation state of Mn}) + 4 \\times (\\text{Oxidation state of O}) = 0(Oxidation\u00a0state\u00a0of\u00a0K)+(Oxidation\u00a0state\u00a0of\u00a0Mn)+4\u00d7(Oxidation\u00a0state\u00a0of\u00a0O)=0 Substituting the known values: (+1)+(Oxidation\u00a0state\u00a0of\u00a0Mn)+4\u00d7(\u22122)=0(+1) + (\\text{Oxidation state of Mn}) + 4 \\times (-2) = 0(+1)+(Oxidation\u00a0state\u00a0of\u00a0Mn)+4\u00d7(\u22122)=0 +1+(Oxidation\u00a0state\u00a0of\u00a0Mn)\u22128=0+1 + (\\text{Oxidation state of Mn}) – 8 = 0+1+(Oxidation\u00a0state\u00a0of\u00a0Mn)\u22128=0 Oxidation\u00a0state\u00a0of\u00a0Mn\u22127=0\\text{Oxidation state of Mn} – 7 = 0Oxidation\u00a0state\u00a0of\u00a0Mn\u22127=0 Oxidation\u00a0state\u00a0of\u00a0Mn=+7\\text{Oxidation state of Mn} = +7Oxidation\u00a0state\u00a0of\u00a0Mn=+7<\/li>\n\n\n\n
    • Conclusion:<\/strong>
      Therefore, the oxidation number of manganese in KMnO4 is +7<\/strong>. This high oxidation state is typical for manganese in permanganate compounds, where it exhibits a strong oxidizing character.<\/li>\n<\/ol>\n\n\n\n

      This oxidation state of +7 is characteristic of the Mn(VII) ion in KMnO4, which is commonly used as an oxidizing agent in various chemical reactions.<\/p>\n\n\n\n
