Question

Of the following solutions, which will have the lowest freezing point?

1 M CaCl2
1 M MgSo4
1 M NaCl
1 M sugar

Answer 1

1 M CaCl2
The van't Hoff factor is the highest in this one as it dissociates into 3 ions. MgSO4 and NaCl dissociate into 2 and sucrose/glucose remains sucrose/glucose...

Answer 2

Thanks!
