On treatment of 100 mL of 0.1 M solution of CoCl3.6H2O with excess AgNO3,1.2×1022 ions are precipitated. The complex is :

Molarity (M)=Volumeofsolution(inL)Numberofmolesofsolute∴ Number of moles of complex=1000Molarity×volume(inmL)=10000.1×100=0.01moleNumber of moles of ions precipitate=6.02×10231.2×1022=0.02mol∴ Number of Cl−present in ionisation sphere =NumberofmolesofcomplexNumberofmolesofionsprecipitated=0.010.02=2∴ 2Cl− are present outside the square brackets, i.e. in ionisation sphere. Thus, the formula of complex is [Co(H2O)5Cl]Cl2.H2O.

Molarity

(M) = \frac{N u mb er o f m o l es o f so l u t e}{V o l u m e o f so l u t i o n ( in L )}

∴

Number of moles of complex

= \frac{M o l a r i t y \times v o l u m e ( in m L )}{1000}

= \frac{0.1 \times 100}{1000} = 0.01 m o l e

Number of moles of ions precipitate

= \frac{1.2 \times 1 0 ^{22}}{6.02 \times 1 0 ^{23}} = 0.02 m o l

∴

Number of

Cl^{-}

present in ionisation sphere

= \frac{N u mb er o f m o l es o f i o n s p rec i p i t a t e d}{N u mb er o f m o l es o f co m pl e x}

= \frac{0.02}{0.01} = 2

∴ 2 Cl^{-}

are present outside the square brackets, i.e. in ionisation sphere.
Thus, the formula of complex is

[C o (H_{2} O)_{5} Cl] Cl_{2} . H_{2} O
