On treatment of 100 mL of 0.1 M solution of

COC{l_3}.6{H_2}O

with excess of

AgN{O_3};\,1.2 \times {10^{22}}

ions are precipitated. The complex is

View answer and explanation

Correct option: D

\left[ {Co{{\left( {{H_2}O} \right)}_5}Cl} \right]C{l_2}.{H_2}O

Option D (

\left[ {Co{{\left( {{H_2}O} \right)}_5}Cl} \right]C{l_2}.{H_2}O

) is correct because it corresponds to the precipitation of 2 chloride ions per complex molecule, matching the given ion precipitation data.
