Colligative Properties of Road Salts
MgCl2 and NaCl are both salts used to treat roads. Based on their colligative properties, which salt has the greatest effect on the freezing point, and why?
A
MgCl2, because i = 2.
B
NaCl, because i = 2.
C
NaCl, because i = 3.
D
MgCl2, because i = 3.
E
Both salts have the same effect.
