  • question_answer When\[AgN{{O}_{3}}\]solution is added in excess to \[1\,\,M\] solution of\[CoC{{l}_{3}}\cdot xN{{H}_{3}}\], one mole of \[AgCl\] is formed. What is the value of\[x\]?

    A)  1                                            

    B)  2

    C)  3                                            

    D)  4

    Correct Answer: D

    Solution :

    When\[AgN{{O}_{3}}\]is added to\[CoC{{l}_{3}}\cdot xN{{H}_{3}}\]one mole of \[AgCl\] is formed hence, the value of\[x\]is 4. \[[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]Cl{{[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]}^{+}}\]                \[+\underset{\begin{smallmatrix}  can\,\,be \\  percipitated \end{smallmatrix}}{\mathop{C{{l}^{-}}}}\,\]
