Q 2633245142.     3.24 g of Hg(NO_3)_2 (molar mass= 324) dissolved in 1000 g of water constitut.es a solution having a
freezing point of - 0.0558°C while 21.68 g of HgCl_2 (molar mass = 271) in 2000 g of water constitutes a solution with a freezing point of -0.0744°C. The K_1 for water is 1.86 (K- K_g)/(Mol) . About the state of ionization of these two solids in water it can be inferred that
A

Hg(NO_3)_2 and HgCl_2 both are completely ionized

B

Hg(NO_3)_2 is fully ionized but HgCl_2 is fully unionized

C

Hg(NO_3)_2 and HgCl_2 both are completely unionized

D

Hg(NO_3)_2 is fully unionized but HgCl_2 is fully ionized
