A linear complex `AgCl. 2NH_3` undergoes complete ionizaiton. What are the ions formed?

AgCl with NH_(3) forms

A coordiante complex contains Co^3, Cl and NH_3 . When dissolved in water , one mole of this complex gave a total of 3 moles of ions . The complex is

(A): One mole of CrCl_3. 5NH_3 in aqueous solutions can give two moles of AgCl on addition with excess AgNO_3 solution (R) : CrCl_3 . 5NH_3 has octahedral shape.

[PtBrCl(NO_(2))(NH_(3))] I on ionisation gives the ion

One mole of the complex compound CoCl_3 xNH_3 gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with two moles of AgNO_3 solution to yield two moles of AgCl. The value of x is
