    \[AgCl\] is soluble in \[N{{H}_{4}}OH\] solution. The solubility is due to formation of:

    A) \[AgOH\]                            

    B)  \[A{{g}_{2}}O\]

    C)  \[{{[Ag{{(N{{H}_{3}})}_{2}}]}^{+}}\] 

    D)         \[N{{H}_{4}}Cl\]

    E)  \[[AgCl(N{{H}_{3}})]\]

    Correct Answer: C

    Solution :

    \[AgCl\]is soluble in\[N{{H}_{4}}OH\]solution. The solubility is due to formation of diammine silver (I) chloride. \[AgCl+2N{{H}_{4}}OH\xrightarrow{{}}\underset{\begin{smallmatrix}  diam\min esilver(l) \\  \,\,\,\,\,\,\,\,\,\,\,\,chloride \end{smallmatrix}}{\mathop{[Ag{{(N{{H}_{3}})}_{2}}]Cl}}\,+2{{H}_{2}}O\]
