3.24 g of Hg(NO_(3))_(2) [M-Wt=324] dissolved in 1000g of water constitutes a solution having freezing point of =0.0558^(@)C while 21.68 "of" HgCl_(2) (molar mass =271) in 2000g of water constitutes a solution with a frezzing point of -0.0744^(@)C. The K_(f) for water is 1.86(K kg)/(mol) . About the state of ionisation of these two solids in water it can be inferred that

Answer»

`HG(NC_(3))_(2) and HgCl_(2)` both are COMPLETELY ionized
`Hg(NO_(3))_(2)` is fully ionized but `Hgcl_(2)` is fully unionized
`Hg(NO_(3))_(2)` and `HgCl_(2)` both are completely unionized
`Hg(NO_(3))_(2)` is fully unionized but `Hgcl_(2)` is fully ionized
