Q:
What is the freezing point of water with sugar?

A:

Solutes decrease the freezing point and increase boiling point of water. For low concentrations, the effect depends only on the number of solute particles per unit volume, as we discuss . For ordinary table sugar (sucrose) each gram that you add to a liter of water will reduce the freezing point about 0.05 °C. At larger concentrations, the effect gets a ligttle more complicated.
