Which of the two has lower freezing point, 2m NaCl or 5m NaCl aqueous solution?
2m NaCl solution
Both have same freezing point
5m NaCl solution
The solutions cannot freeze
Since ΔTf for 5m NaCl will be higher than for 2m, 5m NaCl solution freezes at a lower temperature.
Which of the following aqueous solution has maximum freezing point
.01 M nacl
.05 M c2h5oh
.005 M mgi2
.01 M mgso4
