For the reaction given below :
CoCl3 . xNH3 + AgNO3 (aq) $\to$
If two equivalents of AgCl precipitate out, then the value of x will be _____________.
Answer (integer)
5
Solution
$$
\begin{aligned}
&\mathrm{CoCl}_3 \cdot \mathrm{xNH}_3+\mathrm{AgNO}_3 \rightarrow \underset{\text{2 mol}}{\mathrm{AgCl} \downarrow}\\\\
&\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}\right] \mathrm{Cl}_2+\mathrm{AgNO}_3 \rightarrow \underset{\text{2 mol}}{\mathrm{AgCl}} \downarrow\\\\
&x=5
\end{aligned}
$$
