1. The problem statement, all variables and given/known data Is the freezing point always depressed by a solute even if solute-solvent interactions are stronger than solute-solute and solvent-solvent interaction? What about amorphous solids? 2. Relevant knowledge According to my chemistry teacher's powerpoints, the freezing point is always depressed by the presence of a solute because the solute particles disrupt the lattice structure of the solid. 3. The attempt at a solution Thus, the solution remains liquid at lower than normal temperatures due to the added difficulty of forming the solid structure. The stronger solute-solvent interactions add to this disorder. In amorphous solids where there is little/no organized set structure to speak of, I don't know how solute particles would interfere unless the solute forms its own competing structure as a solid. Otherwise, I'm in the dark.
