question_answer 1)

  Which of the following equations depict the oxidising nature of\[{{H}_{2}}{{O}_{2}}\]? (a)\[2MnO_{4}^{-}+6{{H}^{+}}5{{H}_{2}}{{O}_{2}}\to 2M{{n}^{2+}}+8{{H}_{2}}O+5{{O}_{2}}\]    (b) \[2F{{e}^{3+}}+2{{H}^{+}}+{{H}_{2}}{{O}_{2}}\to 2F{{e}^{2+}}+2{{H}_{2}}O+{{O}_{2}}\] (c) \[2{{I}^{-}}+2{{H}^{+}}+{{H}_{2}}{{O}_{2}}\to {{I}_{4}}+2{{H}_{2}}O\]                                (d) \[KI{{O}_{4}}+{{H}_{2}}{{O}_{2}}\to KI{{O}_{3}}+{{H}_{2}}O+{{O}_{2}}\]

Answer:

  (c)\[2{{I}^{-}}+2{{H}^{+}}+{{H}_{2}}{{O}_{2}}\to {{I}_{2}}+2{{H}_{2}}O\] \[O.N.-1\xrightarrow[\begin{smallmatrix}  Increase\,in\,oxidation \\  number\,(Oxidation) \end{smallmatrix}]{}0\]
