Relative to pure water, an aqueous sugar solution ________. relative to pure water, an aqueous sugar solution ________. has a lower freezing point because crystal formation is inhibited by the sugar molecules has the same freezing point because most of the solution is water molecules has a higher freezing point because crystal formation is promoted by the sugar molecules has a higher freezing point because crystal formation is inhibited by the sugar molecules has a lower freezing point because crystal formation is promoted by the sugar molecules
