    When a dilute solution of ammonia is  saturated with \[{{\text{H}}_{\text{2}}}\text{S}\]it gives

    A) \[{{(N{{H}_{4}})}_{2}}S\]

    B) \[N{{H}_{4}}HS\]

    C)  \[{{(N{{H}_{3}})}_{2}}{{H}_{2}}S\]

    D)  \[N{{H}_{3}}.{{H}_{2}}S\]

    Correct Answer: B

    Solution :

     Ammonium hydrogen sulphide \[(N{{H}_{4}}HS)\] is produced when a dilute aqueous ammonium  solution is saturated with hydrogen sulphide. \[N{{H}_{3}}+{{H}_{2}}S\xrightarrow{{}}N{{H}_{4}}HS\]
