    The nature of\[F{{e}_{2}}{{O}_{3}}\]is

    A)  acidic                   

    B)                         basic

    C)                         amphoteric                       

    D)                         None of these

    Correct Answer: C

    Solution :

    \[F{{e}_{2}}{{O}_{3}}\]is amphoteric in nature as it reacts with both acid and alkali.         \[F{{e}_{2}}{{O}_{3}}+\underset{acid}{\mathop{6HCl}}\,\xrightarrow{{}}2FeC{{l}_{3}}+3{{H}_{2}}O\]        \[F{{e}_{2}}{{O}_{3}}+\underset{alkali}{\mathop{N{{a}_{2}}C{{O}_{3}}}}\,\xrightarrow{{}}2NaFe{{O}_{2}}+C{{O}_{2}}\]
