Which of the following ideal aqueous solutions would be predicted to have the highest freezing point?
1.00 m Na2SO4 |
1.00 m RbCl |
0.50 m KNO3 |
2.00 m methanol (CH3OH) |
highest freezig point ... menas the point that will depress the LEAST
that is given by
dTf = Kf*m*i
since KF is constatn
then
m*i is the factors
for Na2SO4 --< 1*3 = 3
and methanol --> 2*1 = 2
then
the lowest
KNO3 = 0.5*2 = 1
the least number of "m*i" is given by KNO3
