A solution containing $2.675\mathrm{g}$ of ${\mathrm{CoCl}}_3.6{\mathrm{NH}}_3$ (molar mass $=267.5\mathrm{g}{\mathrm{mol}}^{-1}$ ) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of ${\mathrm{AgNO}}_3$ to give $4.78\mathrm{g}$ of $\mathrm{AgCl}$ (molar mass $=143.5\mathrm{g}{\mathrm{mol}}^{-1}$ ). The formula of the complex is (At. Mass of $\mathrm{Ag}=108\mathrm{u}$ )
