One chlorine atom satisfies both primary and secondary valency.

Vedclass · Answer

(B) According to Werner's coordination theory,the chloride ions that are ionizable are those present outside the coordination sphere (primary valency). Since the addition of $AgNO_3$ yields $AgCl$ precipitates corresponding to two chloride ions,it implies that two $Cl^-$ ions are outside the coordination sphere. The formula of the complex is $[Co(NH_3)_5Cl]Cl_2$. In this complex,the $Cl^-$ ion inside the square bracket satisfies both primary and secondary valency,while the two $Cl^-$ ions outside the bracket satisfy only primary valency. Therefore,one chlorine atom satisfies both primary and secondary valency.

If the addition of $AgNO_3$ to a solution of $Co(NH_3)_5Cl_3$ results in the precipitation of $AgCl$ corresponding to two ionizable chloride ions,it means that ..............
