A solution containing 2.675g of CoCl3.6NH3(molar mass=267.5g mol-1) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of AgNo3 to give 4.78g of AgCl(molar mass=143.5g mol-1). The formula of the complex is:(At.mass of Ag=108u)
(b) Meq.of Cl- outside the sphere
= mole of Cl-
=0.033 mole of Cl-
.. Wcl=1.185g
or 0.01 mole of complex gives 0.01xn mole of Cl-
.. 0.01xn=0.033 .. n=3
Thus, formula is [CO(NH3)6]Cl3
