    Among the following, the one which can act as both Bronsted acid as well as Bronsted base is

    A) \[{{H}_{3}}P{{O}_{4}}\]

    B) \[AlC{{l}_{3}}\]

    C)  \[C{{H}_{3}}CO{{O}^{-}}\]

    D) \[{{H}_{2}}O\]

    Correct Answer: D

    Solution :

     Water can behave as both Bronsted acid as well as Bronsted base. \[\underset{\text{acid}}{\mathop{{{H}_{2}}O}}\,\,+\underset{\text{base}}{\mathop{{{H}_{2}}O}}\,{{H}_{3}}{{O}^{+}}+O{{H}^{-}}\]
