An octahedral complex with the formula (\mathrm{CoCl}_3 \cdot \mathrm{nNH}_3) upon reaction with excess of (\mathrm{AgNO}_3) solution gives 2 moles of (\mathrm{AgCl}). Consider the oxidation state of (\mathrm{Co}) in the complex is ' xx '. The value of " x+nx+n " is ______An octahedral complex with the formula (CoCl_3 · nNH_3) upon reaction with excess of (AgNO_3) solution gives 2 moles of

Options

  1. A6
  2. B8
  3. C3
  4. D5

Correct answer

B. 8

Step-by-step solution

An octahedral complex with the formula (CoCl_3 · nNH_3) upon reaction with excess of (AgNO_3) solution gives 2 moles of
x+0−1−2=0x=+3n=5∴x+n=8\begin{aligned} & \mathrm{x}+0-1-2=0 \\ & \mathrm{x}=+3 \\ & \mathrm{n}=5 \\ & \therefore \mathrm{x}+\mathrm{n}=8\end{aligned}
