The elevation of boiling point of 0 . 10 m aqueous CrCl 3 . xNH 3 solution is two times that of 0 . 05 &#160; m aqueous CaCl 2 solution. The value of x is &#8230; &#8230; &#8230; &#8230; . . [Assume 100 % ionisation of the complex and CaCl 2 , coordination number of Cr as 6 , and that all NH 3 molecules are present inside the coordination sphere]

0 . 05 m aqueous CaCl 2 = 0 . 15 molal solution of non electrolyte Since the elevation in boiling point is double so the molality of given solution of complex = 0 . 3 m Hence the complex must be producing three ions in the solution, so its formula = Cr NH 3 5 Cl Cl 2 SO X = 5
