5.33 g of CrCl3 6H2O, which is a 1 : 3 electrolyte, is dissolved in water and is passed through a cation exchanger. The chloride ions in the eluted solution, on treatment with AgNO3 results in 8.61 g of AgCl. The ratio of moles of complex reacted and moles of AgCl formed is 10-2. (Nearest integer) [Molar mass in g mol-1 Cr : 52, Ag : 108, Cl : 35.5, H : 1, O : 16]
