    Moist hydrogen peroxide cannot be dried over cone\[{{H}_{2}}S{{O}_{4}}\]because

    A)  it can catch fire

    B)  it is reduced by\[{{H}_{2}}S{{O}_{4}}\]

    C)  it is oxidised by\[{{H}_{2}}S{{O}_{4}}\]

    D)  it is decomposed by\[{{H}_{2}}S{{O}_{4}}\]

    Correct Answer: D

    Solution :

     Cone\[{{H}_{2}}S{{O}_{4}}\]decomposes\[{{H}_{2}}{{O}_{2}}\]thus\[{{H}_{2}}{{O}_{2}}\]can not be dried over it. \[{{H}_{2}}{{O}_{2}}+|O|\xrightarrow[{}]{{}}{{H}_{2}}O+{{O}_{2}}\] From \[{{H}_{2}}S{{O}_{4}}\]
