  • question_answer A bottle of ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends, the white ammonium chloride ring first formed will be            [IIT 1988]

    A)                 At the centre of the tube            

    B)                 Near the hydrogen chloride bottle

    C)                 Near the ammonia bottle            

    D)                 Throughout the length of the tube

    Correct Answer: B

    Solution :

                    \[N{{H}_{4}}Cl\] ring will first formed near the \[HCl\] bottle because rate of diffusion of \[N{{H}_{3}}\]is more than that of \[HCl\] because \[{{M}_{N{{H}_{3}}}}:{{M}_{HCl}}=17:36.5)\]. SO \[N{{H}_{3}}\]will reach first to the \[HCl\]bottle & will react there with \[HCl\]to form \[N{{H}_{4}}Cl\] ring
