HCI are less soluble in water as the temperature of the solution is increased.
Ionic salt dissociate completely in water particularly in water at low concentration.
The molal freezing point of depression constant for water is 1.85kg/k/mol
therefore depression of freezing point =1.853 x 0.100 x 2.32=0.429 degrees celsius
hence solute freeze at - 0.429 degree celsius
Cr.
Cr is the only element listed that is located in the d-block of the periodic table.
