Solution

The correct option is A $1$ L of $1 M [C o (N H_{3})_{6}] C l_{3}$
$1$ M $[C o (N H_{3})_{6}] C l_{3}$ of $1$ L equals 1 mole ( $M V =$ moles$).
$[C o (N H_{3})_{6}] C l_{3} \to [C o (N H_{3})_{6}]^{3 +} + 3 C l^{-}$
$∴$ three chlorides ions reacts with three moles $A g N O_{3}$ to form $A g C l$ .

Which of the following solutions requires three moles of AgNO3 for the complete precipitation of all the chloride ions present in it?

The correct option is A 1 L of 1M [Co(NH3)6]Cl31 M [Co(NH3)6]Cl3 of 1 L equals 1 mole (MV= moles$).[Co(NH3)6]Cl3→[Co(NH3)6]3++3Cl−∴ three chlorides ions reacts with three moles AgNO3 to form AgCl.
