Which salt NaCl or CaCl2 has a greater effect on freezing point?
Calcium chloride gives more freezing point depression per mole than sodium chloride, but less freezing point depression per gram.
Why does NaCl have a higher boiling point than CaCl2?
So from everything I’ve learned, NaCl would be more effective for the melting, because calcium chloride dissociates into three ions and sodium chloride dissociates into two, so that would make the boiling point of water with calcium chloride higher.
How do you find the weight of NaCl?
The formula of Sodium chloride is NaCl. The atomic mass of sodium is 22.99g/mol, and the atomic mass of chlorine is 35.45gmol. Thus, the formula mass of Sodium chloride is 22.99 + 35.45 = 58.44gmol.
What will be the molecular weight of CaCl2 determined experimentally?
For \[{\text{CaC}}{{\text{l}}_2}\] the theoretical molecular weight is 111. This is same as calculated above. Thus, the molecular weight of \[{\text{CaC}}{{\text{l}}_2}\] determined in its aqueous solution experimentally from depression of freezing point will be less than 111.

Why does CaCl2 lower freezing point of water?
CaCl2 would be more effective at lowering the freezing point. When NaCl breaks up, it breaks up into 2 ions, Na+ and Cl -. When CaCl2 breaks up, it breaks up into 3 ions, Ca2+ and 2(Cl-). The more ions that can be dissociated results in a lower freezing point.
What does CaCl2 do to the freezing point of water?
But you may be asking how salt lowers the freezing point of water. Often, however, cities use calcium chloride (CaCl2), another type of salt, on their icy streets. Calcium chloride is more effective at melting ice because it can break down into three ions instead of two: one calcium ion and two chloride ions.
Why melting point of CaCl2 is less than NaCl?
It is because the distance between the calcium and chloride ions’ nuclei, is less than the distance between the mercury and the chloride ions’ nuclei, given the fact that mercury atom has more number of orbitals and shells than calcium.
