    Ammonia gas dissolves in water to form \[N{{H}_{4}}OH\]. In this reaction water acts as                [KCET (Engg./Med.) 1999]

    A)                 A conjugate base            

    B)                 A non-polar solvent

    C)                 An acid

    D)                 A base

    Correct Answer: C

    Solution :

    \[\underset{\text{Acid}}{\mathop{{{H}_{2}}O\,}}\,+\underset{\text{base}}{\mathop{N{{H}_{3}}}}\,\]⇌\[NH_{4}^{+}+O{{H}^{-}}\].                                 In this reaction \[{{H}_{2}}O\] acts as acid because it donate a proton.
