When `AgNO_(3)` is added to a solution of `Co(NH_(3))_(5)Cl_(3)`, the precipitate of AgCl shows two ionizable chloride ions. This means :
When `AgNO_(3)` is added to a solution of `Co(NH_(3))_(5)Cl_(3)`, the precipitate of AgCl shows two ionizable chloride ions. This means :
A. Two chlorine atoms satisfy primary valency and one secondary valency
B. One chlorine atom satisfies primary as well as secondary valency
C. Three chlorine atoms satisfy primary valency
D. Three chlorine atoms satisfy secondary valency.

Correct Answer - A
As one mole of the complex gives two moles of AgCl this meants that the complex has two ionisable `Cl^(-)` ions in one molecule. Thus two `Cl^(-)` ions satisfy primary valency which third `Cl^(-)` ion satisfy secondary valency .
`[Co(NH_(3))_(5)Cl]Cl_(2) (aq) hArr [Co(NH_(3))_(5)Cl]^(2+) (aq) + 2Cl^(-) (aq)`
