Based from following solutions, which will have the lowest freezing point? . 1 m cacl2. 1 m mgso4. 1 m nacl. 1 m sugar

The freezing point of a salt solution can be determined by knowing the molality of the solution and the Kf of the solvent. It is also important to know the van't Hoff factor which relates to the number of ions dissociated. In this case, since the concentration and the solvent is constant, the greatest number of ions has the lowest freezing point. The answer is A. 1 M CaCl2.

Tolerance to high levels of salinity
