Question

For a solution of 0.849 g of mercurous chloride in 50 g of HgCl2(l) the freezing point depression is 1.24oC. Kf for HgCl2 is 34.3. What is the state of mercurous chloride in HgCl2 ? (Hg - 200, Cl - 35.5)

Options

A.as Hg2Cl2 molecules
B.as HgCl molecules
C.as Hg+ and Cl- ions
D.as Hg22+ and Cl- ions

Solution

1.24 = 34.3 ⇒ M = 469.68
∴ as Hg2Cl2 molecules.
