No.
ammonium nitrate breaks into two ions, NH4+, and NO3-
magnesium sulfate breaks into two ions, Mg++, and SO4--
If all ionic substances completely ionized, the aqueous solution with the lowest freezing point would be
1)0.25m NH4NO3
2)0.30m BaCl2
3) 0.35m LiBr
4) 0.50m Sucrose
5) 0.40m MgSO4
I know that i have to multiply m and i to find the largest delta T. I am just not sure if the values that I got for i are correct.
I know that sucrose is 1.
NH4NO3 = 4
BaCl2 = 3 Are these correct?
LiBr = 2
MgSO4 = 3

so NH4NO3 is 2 and MgS04 is 4?
No, MgSO4 is 2. Look at Bob Pursley's post. You get Mg++ and SO4--. 1 + 1 = 2.
Ok thank you!
so 0.30m BaCl2 has the largest delta T at 0.90 so it has the lowest freezing point. Would you agree?
I agree.
