• # 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

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. $[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]Cl{{[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]}^{+}}$                $+\underset{\begin{smallmatrix} can\,\,be \\ percipitated \end{smallmatrix}}{\mathop{C{{l}^{-}}}}\,$
