Question

Six solutions are made by dissolving a certain amount of each of the six substances in 500. g water. If the freezing point of the each aqueous solution is the same, which substance is added to water in the largest amount, in grams? Assume all ionic compounds dissociate 100% to form ions in solution.

ΔT = iKbmsolute ΔT = –iKfmsolute

 

Select one:
A. (NH4)2CO3
B. KCl
C. The largest mass (g) of substance added is the same for two of the solutions.
D.NH4Cl
E. Insufficient information is provided.
F. NaCl
G. CH3OH
H. MgCl2
 
The correct answer should be "B" or KCl, but I don't understand why
