    \[AgCl\] dissolves in a solution of \[N{{H}_{3}}\] but not in water because:

    A)  \[N{{H}_{3}}\] is a better solvent than \[{{H}_{2}}O\]

    B)  \[A{{g}^{+}}\] forms a complex ion with \[N{{H}_{3}}\]

    C)  \[N{{H}_{3}}\]is a stronger base than \[{{H}_{2}}O\]

    D)  the dipole moment of water is higher than \[N{{H}_{3}}\]

    Correct Answer: B

    Solution :

     \[AgCl\] dissolves in the solution of \[N{{H}_{3}}\] but not in water because Ag+ forms a complex ion with \[N{{H}_{3}}\]. \[AgCl+2N{{H}_{3}}\xrightarrow{{}}\underset{\text{diamine}\,\text{silver}\,\text{(I)chloride}}{\mathop{[Ag{{(N{{H}_{3}})}_{2}}]Cl}}\,\]
