When AgNO3 is added to a solution of Co(NH3)5Cl3 the precipitate of AgCl shows two ionizable chloride ions. This means : (A) Two chlorine atoms satisfy primary valencyand one secondary valency (B) One chlorine atom satisfies primary as wellas secondary valency (C) Three chlorine atoms satisfy primary valency (D) Three chlorine atoms satisfy secondary valency

As one mole of the complex gives two moles of AgCl this means that the complex has two ionisable Cr ions in one molecule. Thus, two Cl- ions satisfy primary valency while third Cl- ion satisfy secondary valency. [Co(NH3)5Cl]Cl2 (aq) leftharpoons [Co(NH3)5Cl]2+ (aq) + 2Cl- (aq)

Q. When AgNO3​ is added to a solution of Co(NH3​)5​Cl3​ the precipitate of AgCl shows two ionizable chloride ions. This means :

Two chlorine atoms satisfy primary valencyand one secondary valency

One chlorine atom satisfies primary as wellas secondary valency

Three chlorine atoms satisfy primary valency

Three chlorine atoms satisfy secondary valency

As one mole of the complex gives two moles of AgCl this means that the complex has two ionisable Cr ions in one molecule. Thus, two Cl− ions satisfy primary valency while third Cl− ion satisfy secondary valency. [Co(NH3​)5​Cl]Cl2​(aq)⇌[Co(NH3​)5​Cl]2+(aq)+2Cl−(aq)

Q. When $A g N O_{3}$ is added to a solution of $C o (N H_{3})_{5} C l_{3}$ the precipitate of AgCl shows two ionizable chloride ions. This means :
