When AgNO_(3) is added to a solution of Co(NH_(3))_(5)Cl_(3), the precipitate of AgCl shows two ionisable chloride ions. This means:

Answer»

Two chlorine ATOMS satisfy PRIMARY VALENCY and one secondary valency
One chlorine atom satisfies primary as well as secondary valency
Three chlorine atoms satisfy primary valency
Three chlorine atoms satisfy secondary valency

Solution :Since the PRECIPITATE of AgCl shows two ionisable chloride ion the complex must have the structure.
`[Co(NH_(3))_(5)Cl]Cl_(2)+2AgNO_(3) to [Co(NH_(3))_(5)Cl](NO_(3))_(2)+2AgCl`
Hence two chlorine atoms satisfy the primary valency and one secondary valency.
