    Potassium permanganate acts as an oxidant in alkaline and acidic media. The final products formed from\[KMn{{O}_{4}}\] in two conditions are respectively:

    A)  \[Mn{{O}^{2-}}\] and \[M{{n}^{3+}}\]  

    B)  \[M{{n}^{3+}}\] and \[M{{n}^{2+}}\]

    C)  \[M{{n}^{2+}}\]and \[M{{n}^{3+}}\]   

    D)  \[Mn{{O}_{2}}\]and \[M{{n}^{2+}}\]

    Correct Answer: D

    Solution :

    In acidic medium \[\overset{+7}{\mathop{KMn{{O}_{4}}}}\,\xrightarrow{{}}\overset{+2}{\mathop{MnS{{O}_{4}}}}\,\] In weak basic medium \[KMn{{O}_{4}}\xrightarrow{{}}Mn{{O}_{2}}\]
