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

The correct answer is a. Cu<\/strong> (Copper).<\/p>\n\n\n\n

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

To understand which element is oxidized in the reaction:<\/p>\n\n\n\n

Cu + FeSO\u2084 \u2192 Fe + CuSO\u2084<\/strong><\/p>\n\n\n\n

We must identify the elements that undergo oxidation and reduction, which involves understanding the transfer of electrons in the reaction. Oxidation is the loss of electrons, while reduction is the gain of electrons.<\/p>\n\n\n\n

    \n
  1. Oxidation States:<\/strong>\n
      \n
    • In elemental copper (Cu), the oxidation state is 0<\/strong>.<\/li>\n\n\n\n
    • In iron(II) sulfate (FeSO\u2084), iron (Fe) has an oxidation state of +2<\/strong> (since sulfate ion SO\u2084\u00b2\u207b has a charge of -2, balancing Fe\u00b2\u207a).<\/li>\n\n\n\n
    • In copper sulfate (CuSO\u2084), copper has an oxidation state of +2<\/strong> (because sulfate again carries a -2 charge, balancing the +2 of copper).<\/li>\n\n\n\n
    • In elemental iron (Fe), the oxidation state is 0<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Determining Oxidation and Reduction:<\/strong>\n
        \n
      • Copper (Cu) goes from an oxidation state of 0<\/strong> to +2<\/strong>. This means copper loses electrons, so it is oxidized<\/strong>.<\/li>\n\n\n\n
      • Iron (Fe) goes from an oxidation state of +2<\/strong> in FeSO\u2084 to 0<\/strong> in elemental Fe. This means iron gains electrons, so it is reduced<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        Thus, copper (Cu)<\/strong> is oxidized because it loses electrons, and iron (Fe)<\/strong> is reduced because it gains electrons.<\/p>\n\n\n\n

        This reaction is a classic example of a redox (reduction-oxidation) process, where one element is oxidized (Cu) and another is reduced (Fe). The sulfate ions (SO\u2084\u00b2\u207b) and oxygen (O) remain unaffected in terms of oxidation state, so they are not involved in the redox process.<\/p>\n\n\n\n

        Redox Reaction Summary:<\/h3>\n\n\n\n
          \n
        • Oxidation<\/strong>: Cu (0) \u2192 Cu\u00b2\u207a (in CuSO\u2084), Cu loses electrons.<\/li>\n\n\n\n
        • Reduction<\/strong>: Fe\u00b2\u207a (in FeSO\u2084) \u2192 Fe (0), Fe gains electrons.<\/li>\n<\/ul>\n\n\n\n

          So, the correct answer is a. Cu<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
