Q. Potassium permanganate acts as an oxidant in alkaline and acidic media. The final products formed from $ KMn{{O}_{4}} $ in the two conditions are respectively:
KEAM
KEAM 2005
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+}} $
E
$ M{{n}^{2+}},Mn{{O}_{2}} $
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}} $
