    \[H{{  }_{2}}{{O}_{2}}\] reduces \[{{K}_{4}}Fe(CN)6\]

    A) in neutral solution

    B) in acidic solution

    C) in non-polar solvent

    D) in alkaline solution

    Correct Answer: B

    Solution :

    When \[{{H}_{2}}{{O}_{2}}\] reduces with\[{{K}_{4}}\left[ Fe{{(CN)}_{6}} \right]\]. It is present in acidic solution. \[2{{K}_{4}}\,\left[ Fe{{(CN)}_{6}} \right]\,\,+{{H}_{2}}S{{O}_{4}}+{{H}_{2}}{{O}_{2}}\,\,\to \,\,\] \[2{{K}_{3}}\,\left[ Fe{{(CN)}_{6}} \right]\,\,+{{K}_{2}}S{{O}_{4}}+2{{H}_{2}}O\,\,\]
