JEE MainChemistryCoordination CompoundsMCQ+4 / −1
A solution containing 2.675g of CoCl3CoCl_3CoCl3​. 6NH3NH_3NH3​ (molar mass = 267.5 g mol–1) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of AgNO3AgNO_3AgNO3​ to give 4.78 g of AgClAgClAgCl (molar mass = 143.5 g mol–1). The formula of the complex is : (At. Mass of Ag = 108 u)
